What does Isaiah 10:9 mean?
Every city is alike to Sargon, the king of the Assyrians. From his arrogant perspective, his armies are unbeatable. Each new city is just more food for their brutal appetites. Each city will fall before them as those who have already been destroyed.Sargon gives a list of where each successive city mentioned is farther south. He is describing the path of the Assyrians as they work their way toward Egypt. The Assyrian king is stating each city falls and is destroyed in the same way. This is including the Syrian capital of Damascus and the Israelite capital of Samaria. He claims nothing and no one can stand in his way.
The Lord, however, is not pleased with Sargon's arrogance. After He has finished using Sargon to bring judgment on His people, He will bring judgment on Sargon (Isaiah 10:12).
