1During the reign of David there was a famine for three successive years, and David sought the face of the LORD. And the LORD said, “It is because of the blood shed by Saul and his family, because he killed the Gibeonites.”
2At this, David summoned the Gibeonites and spoke to them. (Now the Gibeonites were not Israelites, but a remnant of the Amorites. The Israelites had taken an oath concerning them, but in his zeal for Israel and Judah, Saul had sought to kill them.)
