Joshua 10:1-2

1Now it came to pass, when Adonizedek king of Jerusalem had heard how Joshua had taken Ai, and had utterly destroyed it; as he had done to Jericho and its king, so he had done to Ai and its king; and how the inhabitants of Gibeon had made peace with Israel, and were among them;

2That they feared greatly, because Gibeon was a great city, as one of the royal cities, and because it was greater than Ai, and all its men were mighty.1
