Commentary for Job 24:13

They These wicked people are the generation of the Flood, who rebelled because of אור, because of the rain; because it would ascend from the earth, they needed nothing.

Eliphaz’s solution to God’s apparent indifference and inaction was that it if He were seen to react it would preclude the existence of free-will. Job now counters that since these raiders and bandits live in hide-outs, in the wild and hidden from sight, they could be dealt with there by Providence, if it really exists, without anyone knowing about it and without it having any effect on free-will. Similarly, evil-doers fear the light of day, for it reveals their evil. They operate in the dark and at night so as to escape detection. Their demise under similar circumstance would also go undetected. Yet God still does not react.
