2 Samuel 9:10-11

10You, your sons, and your servants are to work the ground for him, and you are to bring in the crops so your master’s grandson will have food to eat. But Mephibosheth, your master’s grandson, is always to eat at my table.” Now Ziba had fifteen sons and twenty servants.

11Ziba said to the king, “Your servant will do all my lord the king commands.” So Mephibosheth ate at David’s table just like one of the king’s sons.
