Job 4:13 - Ellicott's Commentary On The Whole Bible

In thoughts from the visions of the night. — The Book of Genesis exhibits the same idea of revelation through visions of the night, e.g., Job 15:1; Job 20:3; Job 30:11; Job 40:5; Job 41:1; afterwards it is not common, except in the Book of Daniel. The word rendered “thoughts” only occurs once again, in Job 20:2. The “deep sleep” of this place is like a reminiscence of Genesis 2:21; Genesis 15:12. It is used again in Job 33:15, otherwise only once in 1 Samuel 26:12, once in Proverbs 19:15, and once in Isaiah 29:10.
