2 Kings 10:32-36

32So in those days the Lord began to cut off portions of Israel; Hazael [of Aram] defeated them throughout the territory of Israel:

33from the Jordan eastward, all the land of Gilead, the Gadites and the Reubenites and the Manassites, from Aroer, which is by the Arnon River, even Gilead and Bashan.

34Now the rest of the acts of Jehu and everything that he did and all his might, are they not written in the Book of the Chronicles of the Kings of Israel?

35Jehu slept with his fathers [in death], and they buried him in Samaria. Jehoahaz his son became king in his place.

36The time that Jehu reigned over Israel in Samaria was twenty-eight years.
