2 Samuel 21:5-7

The Gibeonites said, “Saul made plans against us and tried to destroy all our people who are left in the land of Israel. So bring seven of his sons to us. Then we will kill them and hang them on stakes in the presence of the LORD at Gibeah, the hometown of Saul, the LORD’s chosen king.” The king said, “I will give them to you.” But the king protected Mephibosheth, the son of Jonathan, the son of Saul, because of the promise he had made to Jonathan in the LORD’s name.
