2 Samuel 9:9-10

9Then the king summoned Saul’s attendant Ziba and said to him, “I have given to your master’s grandson all that belonged to Saul and his family.

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.
