Joshua 9:16–19
Three days after they had made the treaty with the Gibeonites, the Israelites learned that they were neighbors, living among them. / So the Israelites set out and on the third day arrived at their cities—Gibeon, Chephirah, Beeroth, and Kiriath-jearim. / But the Israelites did not attack them, because the leaders of the congregation had sworn an oath to them by the LORD, the God of Israel. And the whole congregation grumbled against the leaders.
Psalm 15:4
who despises the vile but honors those who fear the LORD, who does not revise a costly oath,
