2 Samuel 9:11-13

11Ziba 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.

12Now Mephibosheth had a young son whose name was Mica. All the members of Ziba’s household were Mephibosheth’s servants.

13Mephibosheth was living in Jerusalem, for he was a regular guest at the king’s table. But both his feet were crippled.
