1 Kings 16:22

Now the rest of the acts of Zimri, and his treason that he did, aren't they written in the book of the chronicles of the kings of Israel?

Then were the people of Israel divided into two parts: half of the people followed Tibni the son of Ginath, to make him king; and half followed Omri.

In the thirty-first year of Asa king of Judah began Omri to reign over Israel, [and reigned] twelve years: six years reigned he in Tirzah.

He bought the hill Samaria of Shemer for two talents of silver; and he built on the hill, and called the name of the city which he built, after the name of Shemer, the owner of the hill, Samaria.
