Joshua 10:1-2

1Adoni-zedek, king of Jerusalem, heard that Joshua had captured and completely destroyed Ai and killed its king, just as he had destroyed the town of Jericho and killed its king. He also learned that the Gibeonites had made peace with Israel and were now their allies.

2He and his people became very afraid when they heard all this because Gibeon was a large town—as large as the royal cities and larger than Ai. And the Gibeonite men were strong warriors.
