Joshua 9:16-18

It happened that three days after they had made a covenant (treaty) with them, the Israelites heard that they were [actually] their neighbors and that they were living among them. Then the sons of Israel set out and came to their cities on the third day. Now the cities [of the Hivites] were Gibeon and Chephirah and Beeroth and Kiriath-jearim. But the sons of Israel did not strike them because the leaders of the congregation had sworn to them by the LORD the God of Israel [to spare them]. And all the congregation murmured [expressing great dissatisfaction] against the leaders.
