Rahab is a monster of the primeval sea, its very name meaning turbulence, whom Yahweh vanquishes in the creation-combat. The Psalmist declares that Yahweh crushed Rahab like a carcass and scattered his enemies with his mighty arm, and Job says that by his power he stilled the Sea and by his understanding shattered Rahab, his hand piercing the fleeing serpent. Second Isaiah fuses this myth with the exodus, calling on the arm of Yahweh that of old cut Rahab in pieces and pierced the dragon, that dried up the sea so the redeemed might pass. By extension Rahab becomes a poetic name for Egypt, the historical embodiment of chaos, 'Rahab who sits still'. He is often identified with Leviathan and with the chaos-sea Yam, and is not to be confused with the woman Rahab of Jericho, whose name is spelled differently.
