Job 28:2-6

2Iron is taken out of the dust, and copper is molten out of the stone.

3[Man] putteth an end to the darkness, and exploreth to the utmost limit, the stones of darkness and of the shadow of death.

4He openeth a shaft far from the inhabitants [of the earth]: forgotten of the foot, they hang suspended; away below men they hover.

5As for the earth, out of it cometh bread, and underneath it is turned up as by fire;

6The stones of it are the place of sapphires, and it hath dust of gold.
