Charles Ellicott Commentary Job 28:4

"He breaketh open a shaft away from where men sojourn; They are forgotten of the foot; They hang afar from men, they swing to and fro." — Job 28:4 (ASV)

The flood breaketh out ... is very uncertain. We may render, Man breaketh open a shaft where none sojourneth; they are forgotten where none passeth by: i.e., the laborers in these deserted places hang far from human settlements; they flit to and fro. Or it may be, The flood breaketh out from the inhabitants, even the waters forgotten of the foot: they are dried up, they are gone away from man: that is, the very course of rivers is subject to the will and power of man. Those who walk over the place forget that it was once a river, so completely has man obliterated the marks of it.
