2 Samuel 9:1-4

David asked, “Is anyone still left in Saul’s family? I want to show kindness to that person for Jonathan’s sake!” Now there was a servant named Ziba from Saul’s family. So David’s servants called Ziba to him. King David said to him, “Are you Ziba?” He answered, “Yes, I am your servant.” The king asked, “Is anyone left in Saul’s family? I want to show God’s kindness to that person.” Ziba answered the king, “Jonathan has a son still living who is crippled in both feet.” The king asked Ziba, “Where is this son?” Ziba answered, “He is at the house of Makir son of Ammiel in Lo Debar.”
