Joshua 10:42

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

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

Wherefore Adoni-zedek king of Jerusalem sent unto Hoham king of Hebron, and unto Piram king of Jarmuth, and unto Japhia king of Lachish, and unto Debir king of Eglon, saying,

Come up unto me, and help me, that we may smite Gibeon: for it hath made peace with Joshua and with the children of Israel.
