'Serpent' in the Bible

Don’t rejoice, all of you in Philistia,because the rod of the one who struck you is broken.For a viper will come from the root of a snake,and from its egg comes a flying serpent.

On that day the Lord with His harsh, great, and strong sword, will bring judgment on Leviathan, the fleeing serpent—Leviathan, the twisting serpent. He will slay the monster that is in the sea.

An oracle about the animals of the Negev:Through a land of trouble and distress,of lioness and lion,of viper and flying serpent,they carry their wealth on the backs of donkeysand their treasures on the humps of camels,to a people who will not help them.
