Albert Barnes Commentary 2 Chronicles 24:23

"And it came to pass at the end of the year, that the army of the Syrians came up against him: and they came to Judah and Jerusalem, and destroyed all the princes of the people from among the people, and sent all the spoil of them unto the king of Damascus." — 2 Chronicles 24:23 (ASV)
