'Sea monster' in the Bible

On that day, Yahweh will punish with his cruel, great and strong sword Leviathan, [the] fleeing serpent, and Leviathan, [the] twisting serpent, and he will kill the sea monster that [is] in the sea.

The beast of the field shall know me, the sea monster and the daughters of the ostrich: for I gave waters in the desert, rivers in the waste to give drink to my people, my chosen.

Awake, awake, put on strength, O arm of the LORD; awake, as in the ancient days, in the generations of old. Are you not him who has cut Rahab, and wounded the sea monster?
