2 Samuel 19:29

Now 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.”

So Mephibosheth, the son of Jonathan the son of Saul, came to David and fell on his face and prostrated himself. And David said, “Mephibosheth.” And he said, “Here is your servant!”

Then the king called Saul’s young man Ziba and said to him, “All that belonged to Saul and to all his house I have given to your master’s grandson.

Then Ziba said to the king, “According to all that my lord the king commands his servant so your servant will do.” So Mephibosheth ate at David’s table as one of the king’s sons.
