2 Samuel 21:1-3

During the time David was king, there was a shortage of food that lasted for three years. So David prayed to the LORD. The LORD answered, “Saul and his family of murderers are the reason for this shortage, because he killed the Gibeonites.” (Now the Gibeonites were not Israelites; they were a group of Amorites who were left alive. The Israelites had promised not to hurt the Gibeonites, but Saul had tried to kill them, because he was eager to help the people of Israel and Judah.) King David called the Gibeonites together and spoke to them. He asked, “What can I do for you? How can I make up for the harm done so you can bless the LORD’s people?”
