1 Kings 16:22

for his sins which he sinned in doing that which was evil in the LORD’s sight, in walking in the way of Jeroboam, and in his sin which he did to make Israel to sin.

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

Then the people of Israel were 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, Omri began to reign over Israel for twelve years. He reigned six years 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, Samaria, after the name of Shemer, the owner of the hill.

Omri did that which was evil in the LORD’s sight, and dealt wickedly above all who were before him.
