Adam Clarke on 2 Kings 10:32

The Lord began to cut Israel short - The marginal reading is best: The Lord cut off the ends; and this he did by permitting Hazael to seize on the coasts, to conquer and occupy the frontier towns. This was the commencement of those miserable ravages which Elisha predicted; see 2Kgs 8:12. And we find from the next verse that he seized on all the land of Gilead, and that of Reuben and Gad, and the half tribe of Manasseh; in a word, whatever Israel possessed on the east side of Jordan.
