2 Samuel 9:1-4

1And David said, "Is there still anyone left of the house of Saul, that I may show him kindness for Jonathan's sake?"

2Now there was a servant of the house of Saul whose name was Ziba, and they called him to David. And the king said to him, "Are you Ziba?" And he said, "I am your servant."

3And the king said, "Is there not still someone of the house of Saul, that I may show the kindness of God to him?" Ziba said to the king, "There is still a son of Jonathan; he is crippled in his feet."

4The king said to him, "Where is he?" And Ziba said to the king, "He is in the house of Machir the son of Ammiel, at Lo-debar."
