'Serpent' in the Bible

"Don't rejoice, all of you Philistines, that the rod that struck you is broken, because from the snake's root a viper will spring up, and its offspring will be a darting, poisonous serpent.

At that time, with his fierce, mighty, and powerful sword, the LORD will punish the gliding serpent Leviathan the coiling serpent Leviathan and he will kill the dragon that's in the sea.

"The wolf and the lamb will feed together, and the lion will eat straw like the ox; but as for the serpent its food will be dust! They won't harm or destroy on my entire holy mountain," says the LORD.
