All of the Amorite and Canaanite kings heard how the Lord had dried up the Jordan River. They heard how he had dried it up for the people of Israel until they had gone across it. The Amorite kings lived west of the Jordan. The kings of Canaan lived along the Mediterranean Sea. When all of those kings heard what the Lord had done, their hearts melted away in fear. They weren't brave enough to face the people of Israel anymore.
