Hanun king of the Ammonites, that used David's ambassadors in so shameful a manner, whom David overcame and deposed, and set up this brother in his room; who had showed his dislike of his brother's conduct, and now makes a grateful return to David for his favours; though some say this was Hanun himself, as Jarchi, now become a proselyte, which is not so likely; others take this man to be an Israelite that continued in Rabbah, the metropolis of the Ammonites, after it was taken by David: and Machir the son of Ammiel of Lodebar; the same that brought up Mephibosheth, from whom David received him and took him off of his hands, for which now he requited him, see Sa2 9:5 , and Barzillai the Gileadite of Rogelim; a place that lay under the hills of Gilead (y); it had its name from the "fullers" who dwelt here for the convenience of fountains of water to wash their clothes in.
