Albert Barnes Commentary Job 34:22

"There is no darkness, nor thick gloom, Where the workers of iniquity may hide themselves." — Job 34:22 (ASV)

There is no darkness - No dark cavern which can furnish a place of concealment. The guilty usually take refuge in some obscure place where people cannot detect them. But Elihu says that human beings have no power of concealing themselves in this way from God.

Nor shadow of death - A phrase here signifying deep darkness; see it explained in the notes at Job 3:5.

Where the workers of iniquity may hide themselves - That is, where they may conceal themselves so as not to be detected by God. They may conceal themselves from human notice; they may escape the most vigilant police; they may elude all the officers of justice on earth. But they cannot be hidden from God. There is an eye that sees their lurking places, and there is a hand that will drag them forth to justice.
