Revelation 21:15-17, a golden measuring rod

Ezekiel's reed is plain; John's is gold. Ezekiel never says his measuring man is an angel; John does, and Beale reads of an angel in verse 17 as making that explicit. Ezekiel measures a temple complex in fine detail; John measures a city, with numbers built on twelve and far larger than Ezekiel's.

In Ezekiel the measuring promised that the temple would really be built and kept safe. Beale reads John's measuring the same way: God guarantees his presence with his people and their safety from anything unclean. In 11:1 John measured the temple during the church's trials. Now the whole city is measured and secure.

Ezekiel 40:3 in Greek reads en te cheiri autou en spartion oikodomon kai kalamos metron, in his hand a builder's line and a measuring reed. Revelation 21:15 has eichen metron kalamon chrysoun hina metrese ten polin. Beale calls this a continued allusion to Ezekiel 40:3-5, where measuring promises the temple's establishment and protection; the Greek of Ezekiel uses the verb and noun for measure about thirty times each. For 21:16-17 he adds Zechariah 2:2, where an angelic figure goes to measure Jerusalem's breadth and length, and Ezekiel 40:5, where the wall's breadth and height equal one reed. He reads human measurement as a hint that redeemed humanity, Gentiles included, belongs to the city. Keener says the rod comes from Ezekiel 40:3 and that the measurements were meant to produce awe and repentance (Ezekiel 40:4; 43:10-11). The NIV Cultural Backgrounds Study Bible names Zechariah 2:1-2 and Ezekiel 40-41. The grade is drawn here: the scene is Ezekiel's, but measuring with a reed is not unique to it.
