2 Samuel 9:1-3

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.”
