2 Samuel 21:1-3

American Standard Version

21 And there was a famine in the days of David three years, year after year; and David sought the face of Jehovah. And Jehovah said, It is for Saul, and for his bloody house, because he put to death the Gibeonites. ² And the king called the Gibeonites, and said unto them (now the Gibeonites were not of the children of Israel, but of the remnant of the Amorites; and the children of Israel had sworn unto them: and Saul sought to slay them in his zeal for the children of Israel and Judah); ³ and David said unto the Gibeonites, What shall I do for you? and wherewith shall I make atonement, that ye may bless the inheritance of Jehovah?
