Job 28:6

“The stones of it [are] the place of sapphires, etc.] In some parts of the earth its stones are a quarry of sapphires, put here for all precious stones: this is a most excellent precious stone, of a sky colour, with golden specks, and was one of the stones in the breast plate of the high priest; and by which are represented the pavement under the feet of the God of Israel, the throne of Christ, his bowels and affections for his people, the comeliness of them, and the glory of his church in the latter day, (<022410>Exodus 24:10 28:18 <260126>Ezekiel 1:26 <220514>Song of Solomon 5:14 <250407> Lamentations 4:7) (<235411>Isaiah 54:11); and it hath dust of gold; some parts of the earth abound with…”

“Sapphires are found in alluvial soil near rocks and embedded in gneiss. The ancients distinguished two kinds: 1. The real, of transparent blue: 2.

Sapphires - Compare the note at Isaiah 54:11. The sapphire is a precious stone, usually of a blue color, though it is sometimes yellow, red, violet. green, or white.

In some parts of the earth, the sapphires are mixed with stones, and cut out of them and polished. Hath - The earth continueth. Dust - Distinct from that gold which is found in the mass, both sorts of gold being found in the earth. Job 28:7”

“sapphires: Job 28:16; Exo 24:10; Sol 5:14; Isa 54:11; Rev 21:19 dust of gold: or, gold ore Job 28:7”
