2 Samuel 19:28

So Mephibosheth, the son of Jonathan the son of Saul, came to David and fell on his face and prostrated himself. And David said, “Mephibosheth.” And he said, “Here is your servant!”

And David said to him, “Do not fear, for I will surely show lovingkindness to you for the sake of your father Jonathan, and will restore to you all the land of your grandfather Saul; and you shall eat at my table continually.”

“And 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 and eat of it; nevertheless Mephibosheth your master’s grandson shall eat at my table continually.” Now Ziba had fifteen sons and twenty servants.

Then Ziba said to the king, “According to all that my lord the king commands his servant so your servant will do.” So Mephibosheth ate at David’s table as one of the king’s sons.
