'Dragon' in the Bible

Speak, and say, Thus saith the Lord GOD; Behold, I am against thee, Pharaoh king of Egypt, the great dragon that lieth in the midst of his rivers, which hath said, My river is mine own, and I have made it for myself.

“I will put hooks in your jawsAnd [I will] make the fish of your rivers stick to your scales.And I will pull you up from the midst of your rivers,And all the fish of your rivers will stick to your scales.

Son of man, lift up a lamentation for Pharaoh king of Egypt, and thou hast said unto him: A young lion of nations thou hast been like, And thou art as a dragon in the seas, And thou comest forth with thy flowings, And dost trouble the waters with thy feet, And thou dost foul their flowings.
