Charles Spurgeon Commentary Revelation 21:14

"And the wall of the city had twelve foundations, and on them twelve names of the twelve apostles of the Lamb." — Revelation 21:14 (ASV)

And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb.

Not Peter only, but the whole of the twelve apostles shall have their names in the foundations of that holy city.
