Charles Ellicott Commentary Job 4:13

"In thoughts from the visions of the night, When deep sleep falleth on men," — Job 4:13 (ASV)

In thoughts from the visions of the night. —The Book of Genesis exhibits the same idea of revelation through visions of the night (for example,Job 15:1; Job 20:3; Job 30:11; Job 40:5; Job 41:1). Afterwards, this type of revelation is not common, except in the Book of Daniel.

The word rendered “thoughts” appears only once more, in Job 20:2.

The “deep sleep” mentioned in this passage is reminiscent of Genesis 2:21 and Genesis 15:12. This term is used again in Job 33:15; otherwise, it appears only once in 1 Samuel 26:12, once in Proverbs 19:15, and once in Isaiah 29:10.
