Charles Ellicott Commentary Job 9:13

"God will not withdraw his anger; The helpers of Rahab do stoop under him." — Job 9:13 (ASV)

Proud helpers. —Literally, helpers of Rahab. (Psalms 87:4.) But whether Rahab was Egypt, or a poetical name for the lost archangel, it is impossible to say. If the former, then there is a probable allusion here to the overthrow of Pharaoh and his hosts; but we lack evidence to make it plain. The phrase is evidently used as expressing the very ideal of strength—the race of the giants.
