2 Chronicles 22:1

1 Forsooth the dwellers of Jerusalem ordained Ahaziah, the youngest son of Jehoram , to be king for him; for the thieves of Arabia, that felled into the castles of Judah, had slain all his greater, or elder brethren, which were begotten before him. And Ahaziah, the son of Jehoram, king of Judah, reigned. (And the inhabitants of Jerusalem ordained Ahaziah, the youngest son of Jehoram, to be king for him; for the Arab thieves, who fell upon the tents, or the camps, of Judah, had killed all his elder brothers, who were born before him. And so Ahaziah, the son of Jehoram, the king of Judah, reigned.)

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.

And so Ahaziah, the son of Jehoram, the king of Judah, reigned.)

2 Ahaziah was of two and forty years (Ahaziah was twenty-two years old), when he began to reign, and he reigned one year in Jerusalem; the name of his mother was Athaliah, the daughter of Omri.

3 But he entered by the way of the house of Ahab (But he went in the ways of the house of Ahab); for his mother compelled him to do evil.

4 Therefore he did evil in the sight of the Lord, as the house of Ahab; for they were counsellors to him into his perishing, after the death of his father; (And so he did evil before the Lord, like the house of Ahab; for they were his counsellors after his father's death, yea, unto his perishing;)

5 and he went in the counsel of them. And he went with Joram , the son of Ahab, king of Israel, into battle against Hazael, king of Syria, into Ramoth of Gilead (at Ramoth of Gilead). And men of Syria wounded Joram;
