He cuts out channels in the rocks, and his eye sees every precious thing.
Here Job shows, 1. What a great way the wit of man may go in diving into the depths of nature and seizing the riches of it, what a great deal of knowledge and wealth men may, by their ingenious and industrious searches, make themselves masters of.
Commenting on Job 28:1-11
He cutteth out rivers among the rocks,.... By cleaving rocks asunder in order to find out things of value in the cliffs of them; or by cutting his way through them, the miner opens a course for rivers and floods of water, to drain off from his mines, and so can go on with his works more comfortably, and with success; though sometimes they sink...
He cuts channels to drain off the waters, which hinder his mining; and when the waters are gone, he he is able to see the precious things in the earth.
