(4) 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 labourers in these deserted places, they hang afar from the haunts of men, 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.
