2 Samuel 9:9; 2 Samuel 9:10

9 Then the king called Saul's servant Ziba and said to him, "All that belonged to Saul and to all his house I have given to your master's grandson.

10 "You and your sons and your servants shall cultivate the land for him, and you shall bring in the produce so that your master's grandson may have food; nevertheless Mephibosheth your master's grandson shall eat at my table regularly." Now Ziba had fifteen sons and twenty servants.
