2 Chronicles 22:1-5

Then the inhabitants of Jerusalem made Ahaziah, his youngest son, king in his place, for the band of men who came with the Arabs to the camp had killed all the older sons. So Ahaziah the son of Jehoram king of Judah began to reign.

Ahaziah was twenty-two years old when he became king, and he reigned for one year in Jerusalem. And his mother’s name was Athaliah, the granddaughter of Omri.

He also walked in the ways of the house of Ahab, for his mother was his counselor to act wickedly.

So he did evil in the sight of the Lord like the house of Ahab, for they were his counselors after the death of his father, to his own destruction. Ahaziah Allies with Jehoram of Israel

He also walked by their counsel, and went with Jehoram the son of Ahab king of Israel to wage war against Hazael king of Aram at Ramoth-gilead. But the Arameans wounded Joram.
