2 Samuel 21:1-3

During David's reign there was a severe famine which lasted for three full years. So David consulted the LORD about it, and the LORD said, “Saul and his family are guilty of murder; he put the people of Gibeon to death.” (The people of Gibeon were not Israelites; they were a small group of Amorites whom the Israelites had promised to protect, but Saul had tried to destroy them because of his zeal for the people of Israel and Judah.) So David summoned the people of Gibeon and said to them, “What can I do for you? I want to make up for the wrong that was done to you, so that you will bless the LORD's people.”
