II Samuel 9:6, 10

Now when Mephibosheth the son of Jonathan, the son of Saul, had come to David, he fell on his face and prostrated himself. Then David said, “Mephibosheth?” And he answered, “Here is your servant!”

You therefore, and your sons and your servants, shall work the land for him, and you shall bring in the harvest, that your master’s son may have food to eat. But Mephibosheth your master’s son shall eat bread at my table always.” Now Ziba had fifteen sons and twenty servants.
