2 Samuel 9:9-10

9Then the king summoned Ziba, Saul’s servant, and said to him, “All that belonged to Saul and to all his household I have given to your master’s son.

10So you, you and your sons and your servants will till the land for him, and you will bring in the yield so that your master’s son may have food to eat. But Mephibosheth your master’s son will always eat bread at my table.” Now Ziba had 15 sons and 20 servants.
