Rahab (the sea monster)
A sea monster God cut in pieces — and, confusingly, a name the prophets also use for Egypt.
Rahab is a creature of the deep that God is said to have cut in pieces and pierced. It is also, in Isaiah, a nickname for Egypt: a Rahab that sits still, all noise and no help. The two uses are related — the monster of the sea stands in for the empire across the sea — and the Exodus imagery of waters divided sits underneath both. This is not the Rahab of Jericho, whose name in Hebrew is a different word entirely.
Disputed. Used both for a sea creature and as a byname for Egypt, and the relationship between the two is a matter of reading rather than of statement. Not the same name as Rahab of Jericho.
