2 Chronicles 22:1 Meaning and Commentary

2 Chronicles 22:1

And the inhabitants of Jerusalem made Ahaziah his youngest
son king in his stead
He being the only surviving one of the sons of Jehoram, the same with Jehoahaz, ( 2 Chronicles 21:17 ) who was saved when the rest were taken captive and slain, by his mother Athaliah, and he made his escape, and that she also escaped is clear from ( 2 Chronicles 22:10 )

for the band of men that came with the Arabians to the camp;
that is, of the Philistines, ( 2 Chronicles 21:16 ) , which band seems to be a band or company of thieves and robbers, as the Septuagint, cruel and barbarous, as the action ascribed to them shows:

[for they] had slain all the eldest;
sons of Jehoram; the Philistines and Arabians only carried them away captives, but those slew them in cold blood:

so Ahaziah the son of Jehoram king of Judah reigned;
being declared his successor by the inhabitants of Jerusalem.

2 Chronicles 22:1 In-Context

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.

2 Forty and two years old was Ahaziah when he began to reign; and he reigned one year in Jerusalem: and his mother's name was Athaliah the daughter of Omri.

3 He also walked in the ways of the house of Ahab; for his mother was his counsellor to do wickedly.

4 And he did that which was evil in the sight of Jehovah, as did the house of Ahab; for they were his counsellors after the death of his father, to his destruction.

5 He walked also after their counsel, and went with Jehoram the son of Ahab king of Israel to war against Hazael king of Syria at Ramoth-gilead: and the Syrians wounded Joram.
