2 Samuel 9:11-15

Then Ziba said to the king, “In accordance with everything 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.

Mephibosheth had a young son whose name was Mica. And all who lived in the house of Ziba were servants to Mephibosheth.

So Mephibosheth lived in Jerusalem, because he ate at the king’s table regularly. And he was disabled in his two feet.
