2 Samuel 9:10-13

10And you and your sons and your servants shall till the land for him and shall bring in the produce, that your master's grandson may have bread to eat. But Mephibosheth your master's grandson shall always eat at my table." Now Ziba had fifteen sons and twenty servants.

11Then Ziba said to the king, "According to all that my lord the king commands his servant, so will your servant do." So Mephibosheth ate at David's table, like one of the king's sons.

12And Mephibosheth had a young son, whose name was Mica. And all who lived in Ziba's house became Mephibosheth's servants.

13So Mephibosheth lived in Jerusalem, for he ate always at the king's table. Now he was lame in both his feet.
