The process of mining is described in Job 28:1-11.
Moses speaks of the mineral wealth of Canaan (Deuteronomy 8:9). Job 28:4 is rightly thus rendered in the Revised King James Version,
“He breaketh open a shaft away from where men sojourn; they are forgotten of the foot [that passeth by]; they hang afar from men, they swing to and fro.”
These words illustrate ancient mining operations.
