Meaning
(2.) Another king of the Ammonites of the same name is mentioned, who showed kindness to David during his wanderings (2Sam 10:2). On his death David sent an embassy of sympathy to Hanun, his son and successor, at Rabbah Ammon, his capital. The grievous insult which was put upon these ambassadors led to a war against the Ammonites, who, with their allies the Syrians, were completely routed in a battle fought at "the entering in of the gate," probably of Medeba (2Sam 10:6-14). Again Hadarezer rallied the Syrian host, which was totally destroyed by the Israelite army under Joab in a decisive battle fought at Helam (2Sam 10:17), near to Hamath (1Chr 18:3). "So the Syrians feared to help the children of Ammon any more" (2Sam 10:19).
(3.) The father of Amasa, who was commander-in-chief of Abasolom's army (2Sam 17:25). Jesse's wife had apparently been first married to this man, to whom she bore Abigail and Zeruiah, who were thus David's sisters, but only on the mother's side (1Chr 2:16).
