“And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb.”
King James Version (KJV)
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.
Re 21:14 The wall of the city had twelve foundations. The twelve apostles of the Lamb are foundations of the Church, Jesus Christ being the chief corner-stone (Eph 2:20).
