Job 28:6

a place whose stones are sapphires ¹  and which contains dust of gold; ² 

Ex 24:10; Job 28:16; So 5:14; Isa 54:11; Re 21:19

¹ tn It is probably best to take “place” in construct to the rest of the colon, with an understood relative clause: “a place, the rocks of which are sapphires.”

sn The modern stone known as sapphire is thought not to have been used until Roman times, and so some other stone is probably meant here, perhaps lapis lazuli.

² sn H. H. Rowley (Job [NCBC], 181) suggests that if it is lapis lazuli, then the dust of gold would refer to the particles of iron pyrite found in lapis lazuli which glitter like gold.
