'Fight' in the Bible
All the Amorite kings who lived across the Jordan River to the west and all the Canaanite kings by the Mediterranean Sea became discouraged as soon as they heard that the LORD had dried up the water of the Jordan River for the people of Israel until they had crossed it. They no longer had a will to fight because of the people of Israel.
Joshua told the army, "Don't fear or be dismayed! Be strong and courageous, because this is how the LORD will treat all of your enemies whom you fight."
After all these kings had gathered together, they went out and camped together at the waters of Merom to fight Israel.
because the LORD had hardened their hearts so they would fight Israel in war, be completely destroyed without mercy, and be completely wiped out, as the LORD had commanded Moses.
