2 Kings 10:32-36

32In those days the LORD began to reduce the size of Israel. Hazael defeated the Israelites throughout their territory 33from the Jordan eastward through all the land of Gilead (the region of Gad, Reuben, and Manasseh), and from Aroer by the Arnon Valley through Gilead to Bashan.

34As for the rest of the acts of Jehu, along with all his accomplishments and all his might, are they not written in the Book of the Chronicles of the Kings of Israel?

35And Jehu rested with his fathers and was buried in Samaria, and his son Jehoahaz reigned in his place. 36So the duration of Jehu’s reign over Israel in Samaria was twenty-eight years.
