Job 28:6

Through these operations which carry ruin into the bowels of the earth men, however, find the richest reward. The stones of the heart of the earth are the place of sapphires, and of auriferous dust.

it hath dust of gold "It" refers to the "place" in the first clause, hardly to the sapphire, although a particular kind of sapphire is described as being grained or striated with gold. This, however, can hardly be what is meant by "dust of gold." Instead of ithath dust we might render hehath i. e. man; he finds his way to the place of sapphires and possesses himself of the auriferous earth.
