He went with Joram the son of Ahab to make war against Hazael king of Syria at Ramoth-gilead, and the Syrians wounded Joram.
As among common persons there are some that we call little men, who make no figure, are little regarded, as less valued, so among kings there are some whom, in comparison with others, we may call little kings. This Ahaziah was one of these; he looks mean in the history, and in God's account vile, because wicked.
Commenting on 2 Kings 8:25-29
And he went with Joram the son of Ahab to the war against Hazael king of Syria in Ramothgilead; and the Syrians wounded Joram. (p) Which was a city in the tribe of Gad beyond Jordan.
The Syrians wounded Joram - Ahaziah went with Joram to endeavor to wrest Ramoth-gilead out of the hands of the Syrians, which belonged to Israel and Judah. Ahab had endeavored to do this before, and was slain there; see Kg1 22:3 (note), etc., and the notes there.
