91 And David said, "Is there still anyone left of the house of Saul, that I may show him kindness for Jonathan's sake?" 2 Now there was a servant of the house of Saul whose name was Ziba, and they called him to David. And the king said to him, "Are you Ziba?" And he said, "I am your servant." 3 And the king said, "Is there not still someone of the house of Saul, that I may show the kindness of God to him?" Ziba said to the king, "There is still a son of Jonathan; he is crippled in his feet." 4 The king said to him, "Where is he?" And Ziba said to the king, "He is in the house of Machir the son of Ammiel, at Lo-debar."

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.
