'Monster' in the Bible

Tell him that this is what the Lord GOD says: "Watch out! I'm coming to get you, Pharaoh, king of Egypt! You big monster! You lay in wait in the middle of your waterways and say, "My waterways belong to me! I made them for myself!"

“Son of man, lament for Pharaoh king of Egypt and say to him:You compare yourself to a lion of the nations,but you are like a monster in the seas.You thrash about in your rivers,churn up the waters with your feet,and muddy the rivers.”
