3.21.18 - Revelation 21:18

The construction of its wall was of jasper
Jasper was the last stone in the breastplate of the high priest (Ex. ; ). It was also one of the stones which was Satan’s covering in the garden of God (Eze. ). The light of God’s glory in her midst shines through the jasper walls (Rev. +).

pure gold, like clear glass
Pure and clear are from the same word, καθαρός [katharos] : clean, pure, free from dirt.¹ Solomon’s Temple was overlaid with gold (1K. ). The New Jerusalem is considered the queen in relation to the King, the Lamb. “At Your right hand stands the queen in gold from Ophir” (Ps. ). See Jerusalem Married to God.

The purity of the gold speaks of that which has been tested and refined by fire to remove the dross (Job ; Zec. ; 2Cor. ; 1Pe. ). Those who inhabit the New Jerusalem are now without sin. No mention is made of lesser metals, such as silver or bronze (Isa. ).
