Ahaziah II Chronicles 22

II Chronicles 22:1 "And the inhabitants of Jerusalem made Ahaziah his youngest son king in his stead: for the band of men that came with the Arabians to the camp had slain all the eldest. So Ahaziah the son of Jehoram king of Judah reigned."

Again, this book of the Bible was probably written while Israel was in captivity.

There is a bit of a tangle of names in this chapter. It seems to have come about because Jehoram, king of Judah had close ties with Ahab, king of Israel.

Ahab apparently named a son after Jehoram, king of Judah. Also called Joram.
Jehoram, king of Judah also married a daughter of Ahab.

Notice:

v3 "He also walked in the ways of the house of Ahab: for his mother was his counselor to do wickedly." Talking about Ahaziah.

v4 "Wherefore 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 destruction." Following Ahab's teaching brought him to destruction.

v5 "He walked also after their counsel, and went with Jehoram, the sonof Ahab king of Israel to war against Hazael king of Syria at Ramoth-gilead and the Syrians smote Joram." According to my Bible dictionary Joram is often used in the place of Jehoram, I expect to tell them apart. The names mean the same. One was the king of Judah and the other was the son of Ahab.

Athaliah was the mother of Ahaziah. She was of Ahab's bunch. Ahaziah got killed when he went to visit the king's family in Israel. He was caught up in the change of power in the next chapter. Athaliah ruled in his place and tried to wipe out all the 'seed royal'.

v10 "But when Athaliah the mother of Ahaziah saw that her son was dead, she arose and destroyed all the seed royal of the house of Judah."

She missed one named Joash, the youngest son of Ahaziah. His sister rescued him and hid him in a bedchamber of her husband the priest, Jehoiada. So we see that there were still righteous people in Judah. The line of David was still there.

v12 "And he was with them hid in the house of God six years: and Athaliah reigned over the land."

Nehemiah 13:26 seems appropriate here: "Did not Solomon king of Israel sin by these things? yet among many nations was there no king like him, who was beloved of his God, and God made him king over all Israel: nevertheless even him did outlandish women cause to sin."

Psalm:29:1 "O God, the heathen are come unto thine inheritance; thy holy temple have they defiled; they have laid Jerusalem on heaps."

Ahaziah follows after Ahab's ways, dies and his mother rules.
