2 Kings 10:35

In those days the LORD began to cut away parts of Israel; and Hazael struck them in all the borders of Israel

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

Now the rest of the acts of Jehu, and all that he did, and all his might, aren’t they written in the book of the chronicles of the kings of Israel?

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