"Son of Man, start singing this lamentation for the king of Tyre. Tell him, "This is what the Lord GOD says: "You served as my model, my example of complete wisdom and perfect beauty.

"Son of Man, start singing this lamentation about Pharaoh, king of Egypt. Tell him, "You may have called yourself a lion among nations, but you're a monster at sea. You thrash about in your rivers, muddy the water with your feet, and relieve yourself in the rivers.'
