2 Samuel 9:10-11

10You and your sons and servants are to work the ground for him and bring in the harvest, so that your master’s grandson may 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. 11And Ziba said to the king, “Your servant will do all that my lord the king has commanded.”

So Mephibosheth ate at David’s table1 like one of the king’s own sons.
