2 Samuel 9:10-11

9:10 You will cultivate the land for him – you and your sons and your servants. You will bring its produce and it will be food for your master’s grandson to eat. But Mephibosheth, your master’s grandson, will be a regular guest at my table.” (Now Ziba had fifteen sons and twenty servants.)

9:11 Ziba said to the king, “Your servant will do everything that my lord the king has instructed his servant to do.” So Mephibosheth was a regular guest at David’s table, just as though he were one of the king’s sons.

2 Samuel 19:28

19:28 After all, there was no one in the entire house of my grandfather who did not deserve death from my lord the king. But instead you allowed me to eat at your own table! What further claim do I have to ask the king for anything?”
