2 Kings 10:32-36 - The Death Of Jehu
32 Jehovah began to reduce the size of Israel's territory. King Hazael of Syria conquered all the Israelite territory 33 east of the Jordan, as far south as the town of Aroer on the Arnon River. This included the territories of Gilead and Bashan, where the tribes of Gad, Reuben, and East Manasseh lived.
34 Everything else that Jehu did, including his brave deeds, is recorded in The History of the Kings of Israel. 35 He died and was buried in Samaria. His son Jehoahaz succeeded him as king. 36 Jehu had ruled in Samaria as king of Israel for twenty-eight years.
