Matthew Henry on 2 Samuel 19:31-39
David had already graced the triumphs of his restoration with the generous remission of the injuries that had been done to him; we have him here gracing them with a no less generous reward of the kindnesses that had been shown to him. Barzillai, the Gileadite, who had a noble seat at Rogelim, not far from Mahanaim, was the man who, of all the nobility and gentry of that country, had been most kind to David in his distress. If Absalom had prevailed, it is likely he would have suffered for his loyalty; but now he and his shall be no losers by it. Here is,

Adam Clarke on 2 Samuel 19:32
Barzillai was a very aged man - This venerable person had given full proof of his attachment to David by the supplies he had given him when he lay at Mahanaim, where his case was all but desperate; the sincerity of his congratulations now none can suspect. David's offer to him was at once noble and liberal: he wished to compensate such a man, and he wished to have at hand such a friend.
John Gill on 2 Samuel 19:33
And the king said to Barzillai, come thou over with me,.... Over Jordan; Barzillai came with an intent to accompany the king over Jordan; but the king meant not only to go over Jordan, but when over to go further with him, even to Jerusalem:
and I will feed thee with me in Jerusalem; meaning, that he should dwell with him in his palace, and eat at his table, in return for feeding him at Mahanaim.
