What Was the Tree of Knowledge? The Evidence

Series: Image of God · Part 2 of 3

This is the working file behind The Tree of Knowledge and the Transfer of Dominion, sixth in the Image of God series. That post is the argument. This is the evidence, sorted, with the weak joints labeled. If you want to disagree with me, this is the page to do it from.

How to Tell a Bible Fact From a Bible Theory

A long study session on Genesis 2 and 3 kept hitting the same wall. Sources sounded like they had settled a question they had only interpreted, and popular-level material handed assumptions back as though they were findings. So I stopped trying to answer the question and started sorting the claims instead.

The goal here is not a clean answer to what the tree was. The goal is to know which claims rest on bedrock and which rest on sand, so the gaps can be taught honestly rather than papered over.

Two rules govern the sorting, and both cost me something.

Consensus is not evidence. Five scholars agreeing is one argument repeated, not five confirmations. Novelty is not evidence either: nobody else saying it does not make a reading true. Both are headcount. The question is always textual and canonical support.

Source tier determines the answer. In this session the same questions came back with opposite answers depending on whether the source was a website or a real reference work, and I have flagged the places where that happened. Claims attributed to a named scholar get checked against that scholar’s actual book before the name goes on them.

The categories:

FACT. The text says it plainly, or verifiable background and scholarship establish it.

HEBREW. What the language carries. Lexical and observable.

TRADITION. How interpreters ancient and modern have read it. Reception data, not proof of meaning.

THEORY. Reconstruction filling a gap the text leaves open. Whose theory it is gets named.

FICTION. Readings with no textual or background support, including several of my own.

What Genesis 2 and 3 Actually Say

Tier: FACT. The text says it plainly, or verifiable background establishes it.

There is a command, a crossing, and consequences. God forbids the tree on pain of death (Genesis 2:16-17), they eat (3:6), they are judged and expelled (3:16-24). This is the irreducible core and everything else is built around it.

The text reports exactly two changes at eating. Their eyes were opened and they knew they were naked (3:7). God states that the man has become like one of us, knowing good and evil (3:22). That is the entire factual deposit of what changed. Everything beyond those two is inference, mine included.

God confirms the likeness as real. 3:22 is God speaking, not the serpent. Something genuinely happened. The text affirms the change while refusing to define its mechanism.

Like one of us points at the divine council. The plural matches Genesis 1:26. On Heiser’s framework this is God’s heavenly court rather than the Trinity read backward into the verse. Whatever they became like, it is god-like in the elohim sense.

They did not become omniscient. The first fruit of the knowing is shame at their own bodies, not cosmic knowledge. This is decisive against the totality reading discussed below.

The human is God’s royal image-bearer, commissioned to rule. Genesis 1:26-28 states image and dominion twice in three verses; Psalm 8 restates it. In the ancient Near East, image of a god was royal language: kings were a deity’s living image and planted images of themselves across their territory to mark the reach of their rule. Genesis hands that to all humanity. Verifiable background plus explicit text.

Creation is very good, not perfect. Tov me’od in Genesis 1:31, not tamim. Real work was left to do. The commission is to extend the good, not repair a defective world.

Eden is not the whole world. Specific geography in 2:10-14: four rivers, named lands, named minerals. A place on the earth rather than the planet.

God makes garments of skin and clothes them, after judgment. Genesis 3:21 says God made and clothed. It does not narrate a killing, name an animal, or state that God killed anything. A dead animal is implied by the word skin. The act and the agent are unstated.

What Does Knowing Good and Evil Mean in Hebrew?

Tier: HEBREW. What the language carries. Lexical and observable.

Verified against Theological Lexicon of the Old Testament, Swanson’s Dictionary of Biblical Languages, Walton and Wenham.

The idiom means the capacity to discern good from bad. Yada plus the tov and ra antithesis recurs across roughly five passages, consistently denoting the capacity to discriminate and judge rather than omniscience or sexual experience. Deuteronomy 1:39, children who do not yet know good and bad. 2 Samuel 14:17, David discerning good and evil like an angel of God. 2 Samuel 19:35, Barzillai too old to discern good from bad in food and music. 1 Kings 3:9, Solomon asking for it in order to govern. Isaiah 7:15, the child before he knows to refuse evil and choose good.

One caution I want on the record, because I have heard this claim overstated. It is not the identical phrase five times. It is yada plus the tov and ra pair in related constructions. Say that the pairing recurs and points at discernment. Do not say the exact phrase is locked in five verses.

Ra is the comprehensive opposite of tov, not abstract moral evil. Verified in TLOT and Swanson. Ra covers moral evil, inferior quality, harm and danger, misfortune and affliction, and physical ugliness, unified by one idea: whatever threatens, damages or diminishes life and proper relationship. Deuteronomy 30:15 pairs ra with death and tov with life.

Examples, with the accuracy notes attached. 2 Kings 2:19, ra water that causes barrenness, clean. Jeremiah 24, ra figs that cannot be eaten, clean. Genesis 41:3, the ra cows, which supports the range but means repulsive in appearance rather than inferior in quality, and should be cited that way.

The deeper point is not that the word means bad rather than evil. It is that Hebrew does not split them. Ra is life-diminishing-ness in every register at once.

Walton refuses to confine the idiom to any one sphere. Not moral, judicial, sexual or ritual exclusively, but awareness of which things are conducive to order and which are not, grounded in the Akkadian concept ṭēmu. This supports an order-and-disorder reading over a moral-philosophy reading.

Eat is used non-literally across Scripture. Ezekiel eats a scroll, John eats a scroll, Jeremiah says he ate God’s words. Eating is internalizing. So the verb by itself does not force literal fruit-chewing, which gives the symbolic reading real textual legs without settling anything.

Nachash is lexically loaded. The root consonants yield a word for conjuring or practicing divination, which fits a knowledge-dispensing figure, and also words for shining bronze, which connects to language used elsewhere of divine beings. This is Heiser’s reading. See the disagreement below.

How Jews and Christians Have Read the Tree of Knowledge

Tier: TRADITION. Reception data, not proof of meaning.

Everything in this section is data about how people have read the text. None of it is proof of what the text means.

The dominant modern self-rule cluster. Wenham, Blocher, Köstenberger, Bavinck, Kuyper, Kidner, Mathews. What is forbidden is not the capacity, which they already had as image-bearers, but humans taking their definition of good and bad from themselves and the world rather than from God. Kidner’s plain version is taking one’s knowledge, satisfactions and values from the created world in defiance of the Creator. Mathews adds forfeiture of immortality, tying it to 3:22.

I have benched the word autonomy for teaching. It is a seminary term that sounds like an answer and is not. Ask what they gained autonomy to do that they could not do before and it dissolves. Worse, it may be circular: they had to decide for themselves in order to disobey at all, so saying they gained the ability to decide for themselves describes the act of disobeying and then claims the disobeying granted it. Say it in plain words, that they started taking their definition of good and bad from themselves instead of from God, or admit the mechanism is unstated. Do not hide a gap behind a Latin word.

Mark S. Smith holds the opposite pole, and it is a real named position. Smith reads Genesis 3 as an ascent to moral agency as much as a fall, aligning with Barr, Greenberg, Fishbane and Bechtel. On this reading Adam and Eve act without full moral accountability, in a childlike deficit matching Deuteronomy 1:39 and Isaiah 7:15, and acquire moral knowledge through the transgression. Smith’s sharpest structural claim is that sin proper does not enter until Genesis 4, and that Genesis 3 is the beginning of desire rather than of sin. That relocates culpability out of the garden entirely.

So the two poles are both sourced: rebellion and fall on one side, ascent and maturation with culpability deferred on the other. The modern split maps onto the ancient one.

Second Temple reception runs in three streams, not two.

Advancement and dignity: 1 Enoch calls it the tree of wisdom and frames the gain as wisdom. Jubilees rewrites the scene, with angels instructing Adam, no prohibition mentioned and no interrogation, apparently to restore Adam’s dignity.

Disobedience and evil, in the Dead Sea Scrolls: the scrolls barely touch the fall, with roughly three relevant passages. 4Q423 has the tree desirable to make wise, framed as unfaithfulness. 4Q422 attributes an evil inclination, yetzer, to Adam, importing Flood-narrative language from Genesis 6:5 and 8:21 back onto Genesis 3. 4Q458 treats the tree as cosmic evil to be cut down at the end.

The methodological flag is 4Q422, which is documented early retrojection. Evil inclination is not in Genesis 3; the scroll added it. That is the ancient version of reading later theology backward into the text, and it means the retrofitting started early rather than with us.

The totality reading is rejected by consensus, and it deserves logging anyway. Von Rad held that good and evil functions as a merism meaning everything, on the pattern of heaven and earth. Real pedigree, not fringe. The text kills it: if it meant everything, 3:22 would mean they became omniscient, which would make the serpent right about the upside. They got shame instead. The elegant reading the text will not support.

The nachash as a divine being is a live disagreement between two trusted voices. Heiser says yes: a divine rebel, the shining one or conjurer, drawing from the same primeval-rebellion well as Isaiah 14 and Ezekiel 28. Walton says no: read through Israelite eyes the serpent is not Satan and is not understood as empowered by Satan, but functions as a catalyst rather than a rival deity. Flag this when teaching rather than picking a side quietly. Two voices I trust, opposite reads, same text.

Who Has Dominion Over the Earth in the Bible?

Treating all of Scripture as the word of God, the New Testament interprets the Old, so Luke 4, Colossians 2 and Revelation are legitimate commentary on Genesis 3 rather than weaker evidence. The teaching discipline is to show the seam between what is on the surface of Genesis and what the rest of the canon reveals, not to downgrade the New Testament.

Given, then lost, then claimed, then recovered, then consummated. The chain holds end to end with real texts at every link.

Given: Genesis 1:26-28 and Psalm 8. Dominion to humanity as image-bearers.

Lost: Genesis 3:17-19, the ground cursed and toil imposed; Romans 8:19-22, creation subjected to futility.

Claimed: Luke 4:5-8, this authority has been delivered to me; John 12:31, 14:30 and 16:11 on the ruler of this world; 2 Corinthians 4:4 on the god of this age; 1 John 5:19.

Recovered, at the cross and resurrection: Colossians 2:15, disarming the rulers and triumphing over them in the cross; Matthew 28:18; 1 Corinthians 15:24-28; Hebrews 2:5-9 applying Psalm 8 to Jesus; Romans 5:12-21.

Keys held: Revelation 1:18. Possession stated, no struggle narrated.

Consummated: Revelation 11:15 and 5:9-10.

Luke 4:6 is the strongest single text, and Heiser confirms the reading. The Unseen Realm p. 340: the authority offered was real rather than hollow, and Satan’s lordship over the nations disinherited at Babel per Deuteronomy 32 was presumed by the New Testament period. Jesus does not dispute the claim; he rejects the method, because Yahweh will take the nations back by his own means in his own time and does not need them handed over in a bargain.

Note carefully that Heiser routes the handover through Babel and Deuteronomy 32 rather than primarily through Eden. That is a richer and more textually anchored wiring than saying Adam handed the keys to the snake in the garden, and it means my garden-as-hinge reading is a step past his.

The Greek paradidōmi, delivered, is the same verb used of Judas, so it can be read as betrayed into my hands, which fits.

Scholars split three ways on whether the claim is legitimate, a lie in the mouth of the father of lies, or a real influence overstated. Jesus’s silence does not settle it. Teach it as the strongest reading with Heiser’s backing, not as flat fact.

My own selective-correction argument is that Jesus rebuts the other two temptations and not this one, and that selective silence from someone correcting everything else means something. I think it is good reasoning and it points where Heiser points. It is not airtight, because refusing a deal is not the same act as conceding a title, and I have not yet found it in a commentary.

Common Theories About What the Tree of Knowledge Was

Tier: THEORY. Reconstruction filling a gap the text leaves open.

They were on a trajectory to inherit the prerogative. Held by Mackie, by Reformed covenant theology, and implied by Smith’s maturation reading. Status: inference, not stated. There is no until I tell you in the text and no described reward path, and you shall surely die reads as a permanent fatal boundary rather than a temporary hold. The honest version is not this way rather than not yet.

An animal was killed to make the skin garments. Common inference. Genesis 3:21 implies a dead animal but never says so, names it, or narrates a killing. Status: reasonable inference, not stated. The weight usually piled on it, as first sacrifice or a foreshadowing of substitutionary atonement, is tradition layered on a verse that only says God made and clothed. Walton specifically rejects the sacrifice reading, calls it a serious error to read sacrifice between the lines, considers investiture and rejects that too on the grounds that they are being demoted rather than elevated, and lands on grace and covering, preparing them for a harder world. One correction worth stating: the claim that investiture is the reading of Smith and Walton, which circulates, is false. Walton rejects investiture and Smith does not address the verse.

The tree is a real tree that also functions as a sign. A thing can be literally real and also signify; a wedding ring is real metal and means something. This resolves the symbol-versus-fruit tension. The scroll-eating pattern supports the representational half. What it is a sign of remains unrecoverable, for the reason below.

The knowledge tree’s specific symbolism cannot be recovered from background. Smith’s observation, and it is the most useful single thing in this file. There is no ancient Near Eastern parallel to a tree of knowing good and evil. Life-giving trees do have parallels, including the plant of rejuvenation in Gilgamesh, lost to a snake, so the tree of life has background furniture around it. The tree of knowledge is a Genesis original. The consequence is that every confident decoding of its symbolism, mine and Heiser’s and everyone’s, is reconstruction without a template.

Disobedience as a transfer of allegiance away from God. Grounded. Middleton’s point is that in the Old Testament obedience is allegiance, and the life of a person reflects the sort of god they are committed to. Trusting the serpent’s word over God’s about good and bad is a shift of allegiance from Creator to creature.

My own framework, and where it outruns the scholarship. I have wanted to read eating as enthroning the serpent’s word, functioning as worship, and therefore as the handover of the keys. I am naming it as mine because my own trusted voices either do not go there or block the premise. Heiser frames the serpent as a rebel who disrupts order but does not say that eating enthrones it or transfers worship to it. Walton denies the serpent is a deity at all, which takes the footing out from under worshiping the serpent. What survives is the relocation: from worship of the serpent to withdrawal of trust from God, which is the allegiance shift above, and that version is grounded. The enthronement and handover framing gets taught as my framework with the seam showing.

Myths About the Fall That the Bible Does Not Support

Tier: FICTION. No textual or background support, including several of mine.

Readings with no textual or background support, including several I generated myself.

The tree was literally a fig. No textual support. The fig leaves in 3:7 are what they cover themselves with afterward. The fruit is never named.

The forbidden act was killing an animal, taking life and death into their own hands. This was mine, and it has no textual hook. The verbs are eating, repeatedly and explicitly. The only implied animal death is 3:21, God making garments after the judgment with no killing narrated, which sits on God’s side of the ledger and cuts against the theory rather than for it. The supports I offered myself, that they must have known death, that naked means vulnerable, that God clothed them in skin, each fail to require an animal killing at the tree.

They had no idea what death was. Partially corrected in my favor. The serpent’s you will not surely die only works as a temptation if death is a known and weighable threat, so they had some real grasp of it. This does not get anywhere near the animal-killing theory, since knowing what death is and having caused one are different things.

The world was a perfect paradise that the fall broke. The pop-Christian default, contradicted by the geography and by the vocabulary.

Jesus went to hell and won the keys back from Satan in combat, and Paul says so. Fused tradition, and worth flagging loudly. It stitches Revelation 1:18 on the keys, Ephesians 4:9 on the descent and 1 Peter 3:19 on the spirits in prison into a single claim that none of them makes alone, and then misattributes the result to Paul.

Verified against Emerson’s He Descended to the Dead, van der Kooi and van den Brink’s Christian Dogmatics and Jeremias in TDNT: the keys claim rests on Revelation 1:18 alone. 1 Peter 3:19 is heavily contested, with a major reading taking it as Christ preaching through the Spirit in Noah’s day rather than a post-mortem descent. The harrowing tradition was originally about whether the Old Testament saints share in Christ’s victory, not about combat with Satan; the seizing-the-gates motif is later theology added on top. No serious source connects the descent to recovering Adamic dominion.

This is the clearest source-tier lesson in the file. Popular sources confirmed the combat fusion confidently. The real reference works took it apart. Same question, opposite answers, sorted entirely by where I looked.

The correct shape is that the victory was finished at the cross. Any descent is collection, not combat: walking in to take back what is already yours by right, with the outcome already settled. Revelation 1:18 says I have the keys, which is possession stated, not I fought for them. Recovery runs through the cross and resurrection. Making the descent the climax accidentally weakens the cross.

What We Know and What Nobody Can Tell You

What we can stand on: the idiom means the capacity to discern good from bad. Ra is the whole opposite-of-life range rather than abstract evil. The human is a royal image-bearer commissioned to extend a good but unfinished world. The transgression’s core is crossing a divinely set boundary. At eating, only two changes are reported, shame and a real God-confirmed likeness. The knowledge tree has no ancient Near Eastern parallel, so its symbolism cannot be decoded from background. The dominion chain holds canon-wide, with Heiser confirming the Luke 4:6 handover. Recovery runs through cross and resurrection rather than a combat descent.

What nobody can tell you: what the tree really symbolized, what eating added to a being who already had moral capacity and the office, whether they were going to inherit the prerogative, and the mechanism behind the likeness.

The text is reticent on purpose. It gives a command, a crossing, a likeness, a shame, and a chain of dominion lost and recovered, and it withholds the inner mechanism of the tree. Every tradition that solved it had to add something: an evil inclination at Qumran, autonomy in the Reformed tradition, maturation in Smith, sexual awakening in others, and serpent-worship in my own first draft. Name what the text says. Refuse to dress the gap.
