What does Job 28:4 mean?

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.

The flood breaketh out from the inhabitant; even the waters forgotten of the foot: they are dried up, they are gone away from men.

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.

He makes a deep mine far away from those living in the light of day; when they go about on the earth, they have no knowledge of those who are under them, who are hanging far from men, twisting from side to side on a cord.

A stream hath broken out from a sojourner, Those forgotten of the foot, They were low, from man they wandered.

The flood divideth from the people that are on their journey, those whom the food of the needy man hath forgotten, and who cannot be come at.

He openeth a shaft far from the inhabitants [of the earth]: forgotten of the foot, they hang suspended; away below men they hover.
