Joshua 9:16-18 CSB
Three days after making the treaty with them, they heard that the Gibeonites were their neighbors, living among them. So the Israelites set out and reached the Gibeonite cities on the third day. Now their cities were Gibeon, Chephirah, Beeroth, and Kiriath-jearim. But the Israelites did not attack them, because the leaders of the community had sworn an oath to them by the LORD, the God of Israel. Then the whole community grumbled against the leaders.
