2 Samuel 9:2-3

2Now there was a servant of Saul’s household named Ziba. They summoned him to appear before David, and the king said to him, “Are you Ziba?” “At your service,” he replied.

3The king asked, “Is there no one still alive from the house of Saul to whom I can show God’s kindness?” Ziba answered the king, “There is still a son of Jonathan; he is lame in both feet.”
