He bindeth the floods from overflowing. This, again, may be either taken generally of man's ability to create dams, dykes, and embankments, whereby the overflow of waters is prevented; or specially of such works when connected with mines, from which it is possible, in some instances, to dam out water that would otherwise interfere with their working.
The word translated "overflowing" means probably "weeping," and seems to point to that leakage from the roofs and sides of galleries and adits which is more difficult to control and stop than even subterranean springs or rivers.
And the thing that is hid bringeth he forth to light. This is the final result of mining operations. Things useful or beautiful that are hiddden deep down in the heart of the earth, and that might have seemed wholly inaccessible, are brought out of the pit's month into the light of day for the service and delectation of mankind.
