2 Samuel 9:10-11

10You and your sons and your servants are to farm the land for him and bring in the crops, so that your master’s grandson may be provided for. And Mephibosheth, grandson of your master, will always eat at my table.” (Now Ziba had fifteen sons and twenty servants.) 11Then Ziba said to the king, “Your servant will do whatever my lord the king commands his servant to do.” So Mephibosheth ate at David’s table like one of the king’s sons.
