3 And the king said, Is there not yet any of the house of Saul, that I may shew the kindness of God to him? And Ziba said to the king, Jonathan has yet a son, who is lame on [his] feet. 4 And the king said to him, Where is he? And Ziba said to the king, Behold, he is in the house of Machir the son of Ammiel, in Lodebar. 5 And king David sent, and fetched him out of the house of Machir the son of Ammiel, from Lodebar. 6 And Mephibosheth, the son of Jonathan, the son of Saul, came to David, and fell on his face and did obeisance. And David said, Mephibosheth. And he said, Behold thy servant! 7 And David said to him, Fear not; for I will certainly shew thee kindness for Jonathan thy father's sake, and will restore thee all the land of Saul thy father; and thou shalt eat bread at my table continually.

Commentary on 2 Samuel 9:1-8

(Read 2 Samuel 9:1-8)

Amidst numerous affairs we are apt to forget the gratitude we owe, and the engagements we are under, not only to our friends, but to God himself. Yet persons of real godliness will have no rest till they have discharged them. And the most proper objects of kindness and charity, frequently will not be found without inquiry. Jonathan was David's sworn friend, therefore he shows kindness to his son Mephibosheth. God is faithful to us; let us not be unfaithful to one another. If Providence has raised us, and our friends and their families are brought low, we must look upon that as giving us the fairer opportunity of being kind to them.
