Whale

The Hebrew original translated “great whales”
(Gen. 1:2121And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good. (Genesis 1:21)) is used of “serpents” (Ex. 7:99When Pharaoh shall speak unto you, saying, Show a miracle for you: then thou shalt say unto Aaron, Take thy rod, and cast it before Pharaoh, and it shall become a serpent. (Exodus 7:9); Deut. 32:3333Their wine is the poison of dragons, and the cruel venom of asps. (Deuteronomy 32:33)), and of the “crocodile” (Ezek. 29:3; 32:23Speak, 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. (Ezekiel 29:3)
2Son of man, take up a lamentation for Pharaoh king of Egypt, and say unto him, Thou art like a young lion of the nations, and thou art as a whale in the seas: and thou camest forth with thy rivers, and troubledst the waters with thy feet, and fouledst their rivers. (Ezekiel 32:2)
). The name belongs to sea monsters (Job 7:1212Am I a sea, or a whale, that thou settest a watch over me? (Job 7:12); Isa. 27:11In that day the Lord with his sore and great and strong sword shall punish leviathan the piercing serpent, even leviathan that crooked serpent; and he shall slay the dragon that is in the sea. (Isaiah 27:1)). It is thought that the shark of the Mediterranean is meant (Jonah 1:1717Now the Lord had prepared a great fish to swallow up Jonah. And Jonah was in the belly of the fish three days and three nights. (Jonah 1:17); Matt. 12:4040For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth. (Matthew 12:40)).
