John the Apostle
Revelation 21:21KJV·traditional attribution

And the twelve gates were twelve pearls; every several gate was of one pearl: and the street of the city was pure gold, as it were transparent glass.

Matthew Henry Presbyterian

We have already considered the introduction to the vision of the new Jerusalem in a more general idea of the heavenly state; we now come to the vision itself, where observe, I. The person that opened the vision to the apostle - one of the seven angels, that had the seven vials full of the seven last plagues, Rev 21:9.

Commenting on Revelation 21:9-27

John Gill Reformed Baptist

And I saw no temple therein,.... No material temple, as was in the old Jerusalem, or such as is described in Ezekiel's vision; nor any place of public worship, as under the Gospel dispensation; for in this state there will be no such external form of worship as now, such as preaching the word and administering ordinances. The Jews expect a third temple, but in vain.

Albert Barnes Presbyterian

Verse 21. And the twelve gates. . Were twelve pearls. . Every several gate was of one pearl. Each gate. Of course, this is not to be understood literally. The idea is that of ornament and beauty, and nothing could give a more striking view of the magnificence of the future abode of the saints. And the street of the city was pure gold.
