2 Samuel 21:1-2, 7
2 Samuel 21:1-2 NIV
During the reign of David, there was a famine for three successive years; so David sought the face of the LORD. The LORD said, “It is on account of Saul and his blood-stained house; it is because he put the Gibeonites to death.” The king summoned the Gibeonites and spoke to them. (Now the Gibeonites were not a part of Israel but were survivors of the Amorites; the Israelites had sworn to spare them, but Saul in his zeal for Israel and Judah had tried to annihilate them.)
2 Samuel 21:7 NIV
The king spared Mephibosheth son of Jonathan, the son of Saul, because of the oath before the LORD between David and Jonathan son of Saul.
