Verse 1. - Is there yet any that is left of the house of Saul? As Mephibosheth was five years old at his father's death (2 Samuel 4:4), but now had a son (ver. 12), a sufficient time must have elapsed for him to grow up and marry; so that probably the events of this chapter occurred seventeen or eighteen years after the battle of Gilboa. As David was king at Hebron for seven years and a half, he had been king now of all Israel for about nine years. But during this long period he had been engaged in a weary struggle, which had left him little repose, and during which it might have been dangerous to draw the house of Saul out of obscurity. But he was at last firmly established on the throne, and had peace all around; and the time was come to act upon the promise made to Jonathan (1 Samuel 20:14, 15), and which we may be sure David had never forgotten.

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.And David said,.... To some of his courtiers:

is there yet any that is left of the house of Saul? which question was put by him, not in order to destroy them, lest they should disturb his government, as was usual with other princes, and especially such who got their crowns by usurpation; but to prevent any suspicion of that kind in the persons he inquired of, he adds:

that I may show him kindness, for Jonathan's sake? not for Saul's sake, who had been his implacable enemy, though he had sworn to him that he would not cut off his seed; but for Jonathan's sake, his dear friend, whose memory was precious to him. Some of the Jewish writers have thought, because this follows upon the account given of the officers of David, both in his camp and court, that this question was occasioned by a thought that came into his mind, while he was appointing officers, that if there were any of Saul's family, and especially any descendant of Jonathan, that was fit for any post or office, he would put him into one; but this seems to be a long time after David had settled men in his chief offices; for Mephibosheth, after an inquiry found out, was but five years of age when his father was slain, and so but twelve when David was made king over all Israel, and yet now he was married, and had a young son, 2 Samuel 9:12; so that it was a long time after David was established in the kingdom that he thought of this; which is to be imputed to his being engaged so much in war, and having such a multiplicity of business on his hands.
