Joshua 10:1-2

1Now it came to pass when Adoni-Zedek king of Jerusalem 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, like one of the royal cities, and because it was greater than Ai, and all its men were mighty.
