Revelation 21:19 - Exposition

And the foundations of the wall of the city were garnished with all manner of precious stones. Omit "and" (cf. Isaiah 54:12 , "All thy borders of pleasant stones"). Foundations (cf. Revelation 21:14 ). The first foundation was jasper. Probably the diamond (see on Revelation 4:3 ). The second, sapphire. Thought to be the modern lapis lazuli. It was of a clear blue colour ( Exodus 24:10 ), and very precious ( Job 28:16 ). The third, a chalcedony. Not the modern stone of that name, but a green carbonate of copper, found in the mines of Chalcedon. It was, therefore, a kind of inferior emerald. The fourth, an emerald. The same as the modern stone (cf. Revelation 4:3 ).
