2 Chronicles 22:1

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 The inhabitants of Yerushalayim made Achazyah his youngest son king in his place; for the band of men who came with the `Aravi'im to the camp had slain all the eldest. So Achazyah the son of Yehoram king of Yehudah reigned.

2 Forty-two years old was Achazyah when he began to reign; and he reigned one year in Yerushalayim: and his mother's name was `Atalyah the daughter of `Omri.

3 He also walked in the ways of the house of Ach'av; for his mother was his counselor to do wickedly.

4 He did that which was evil in the sight of the LORD, as did the house of Ach'av; for they were his counselors after the death of his father, to his destruction.

5 He walked also after their counsel, and went with Yehoram the son of Ach'av king of Yisra'el to war against Haza'el king of Aram at Ramot-Gil`ad: and the Aram wounded Yoram.
