2 Samuel 21:1-2

Living Bible

21 There was a famine during David’s reign that lasted year after year for three years, and David spent much time in prayer about it. Then the Lord said, “The famine is because of the guilt of Saul and his family, for they murdered the Gibeonites.”

² So King David summoned the Gibeonites. They were not part of Israel but were what was left of the nation of the Amorites. Israel had sworn not to kill them; but Saul, in his nationalistic zeal, had tried to wipe them out.
