Job 28:2-6

Iron is taken out of the earth, and brass is molten out of the stone.

He setteth an end to darkness, and searcheth out all perfection: the stones of darkness, and the shadow of death.

The flood breaketh out from the inhabitant; even the waters forgotten of the foot: they are dried up, they are gone away from men.

As for the earth, out of it cometh bread: and under it is turned up as it were fire.

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