Joshua 9:16-18

And it happened at the end of three days, after they had made a covenant with them, that they heard that they were their neighbors who dwelt near them. Then the children of Israel journeyed and came to their cities on the third day. Now their cities were Gibeon, Chephirah, Beeroth, and Kirjath Jearim. But the children of Israel did not attack them, because the rulers of the congregation had sworn to them by the LORD God of Israel. And all the congregation complained against the rulers.
