Genesis 17:17
Abraham fell upon his face, and laughed. The verb tsachak becomes his son's name, Yitzchak, Isaac, he laughs.
Genesis 17:17, in every translation this tool compares.
Imagine naming a baby Chuckles because both parents laughed, separately, at the news he was coming, and the joke gets repeated every time someone says his name for the rest of the story. Genesis does exactly this, in Hebrew sound, and English Isaac carries none of the joke.
Because Abraham's laughter at the promise of a son is the first appearance of a pun that repeats twice more across the next four chapters, laughter becoming the very name of the child it is aimed at, a running joke Genesis keeps returning to that a bare English name, Isaac, cannot signal even once.
Every version reads laughed here, correctly, and later reads Isaac as a bare proper name at his birth, with no way for an English reader to hear that the name is the same word as the laughter that preceded it, twice.
צָחַק tsachak (יִצְחָק Yitzchak, Isaac) · H6711 / H3327
Tsachak, laughed, here at Abraham's reaction, becomes the root of Yitzchak, Isaac, he laughs or he will laugh, the name eventually given to the promised son. The same pun recurs when Sarah laughs at the promise in Genesis 18:12, and again when Sarah declares after his birth, at 21:6, God hath made me to laugh, so that all that hear will laugh with me, using the same root a third time. The child's very name is the family's skepticism, turned by the end of the story into shared joy, permanently recorded in one repeated Hebrew sound.
English Isaac is a bare transliterated name carrying no meaning at all to an English ear, so the running pun, laughter at disbelief becoming laughter at fulfillment, three separate times across three chapters, is entirely invisible unless a reader is told the name means laughs.
When a child's name is given following a strong emotional reaction, check whether the name and the reaction share a root. Genesis does this repeatedly, and the pun is often built to recur more than once, turning a single naming moment into a thread running through several later chapters.
Laughed and the transliterated name Isaac are both settled; nothing here divides translators. What's worth flagging is that the pun tying them together, and its later repetitions at 18:12 and 21:6, depends entirely on hearing tsachak inside Yitzchak, something no English rendering of either word can supply on its own.
- The same pun recurring at Sarah's laughter: Genesis 18:12
- The pun completed at Isaac's birth: Genesis 21:6
