2Kgs 10:32-33

Death of Jehu 32In those days the Lord began to trim off parts of Israel. Hazael defeated them throughout the territory of Israel:33from the Jordan eastward, all the land of Gilead, the Gadites, the Reubenites, and the Manassites, from Aroer, which is by the Wadi Arnon, that is, Gilead and Bashan.
