Revelation 21:14

The wall - had twelve foundations - Probably twelve stones, one of which served for a foundation or threshold to each gate; and on these were inscribed the names of the twelve apostles, to intimate that it was by the doctrine of the apostles that souls enter into the Church, and thence into the New Jerusalem.

And the wall of the city had twelve foundations - It is not said whether these foundations were twelve rows of stones placed one above another under the city, and extending round it, or whether they were twelve stones placed at intervals. The former would seem to be the most probable, as the latter would indicate comparative feebleness and liability to fall. Compare the notes on Revelation 21:19.

And in them - In the foundation of stones. That is, the names of the apostles were cut or carved in them so as to be conspicuous.

The names of the twelve apostles of the Lamb - Of the Lamb of God; the Messiah. For an illustration of this passage, see the notes on Ephesians 2:20.

21:14 And the wall of the city had twelve foundations, and on them the names of the twelve apostles of the Lamb - Figuratively showing that the inhabitants of the city had built only on that faith which the apostles once delivered to the saints.
