2 Samuel 9:13

‘ So Mephibosheth dwelt in Jerusalem, for he ate continually at the king’s table. And he was lame in both his feet.’

So from this time on Mephibosheth dwelt in Jerusalem, the royal city, and ate continually at the king’s table. David proved to be as good as his word. The reference to the fact that he was lame in both his feet is probably intended to underline David’s generosity. Many another would have dismissed such a person as not fit to live in the royal city and sit at the king’s table, especially as he would be excluded from the court of the Tent of Meeting. But in David’s eyes he stood in the place of Jonathan his friend.
