Job 28:9-11

He putteth forth his hand upon the rock, &c. He digs through the hardest rocks by his obstinate labour; and undermines mountains, that he may find the treasures hid in their bowels. He cutteth out rivers among the rocks If he meets with waters in his mining, which hinder his work, he cuts a channel through the rocks to convey them away; or, if he wants water, to wash the ore, he, with incredible industry, cuts channels to bring it into the mines. And his eye seeth every precious thing Having with great art, and indefatigable industry, broke through all difficulties, he at last arrives at the wished-for object, and finds those precious treasures which he sought for. He bindeth the floods from overflowing He restraineth them, and, as it were, bindeth them to their good behaviour, that they may not overflow the mine. Or, by his industry and skill he confineth the rivers, so that they cannot overflow. And the thing that is hid bringeth he forth to light Those metals, or precious stones, which lie hid in the secret parts of the earth, he discovers to himself and others.
