Charles Ellicott Commentary 2 Chronicles 22:5

"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." — 2 Chronicles 22:5 (ASV)

He walked also after (in) their counsel.—This is an allusion to Psalms 1:1. He became a close partner in the politics of his ally, and joined in his expedition against the Syrians. These words are not in Kings.

And went with Jehoram.—2 Kings 8:28, “Joram.”

King of Israel.—Added by the chronicler.

Against.—In Kings, it is “with.”

Hazael king of Syria.—See Note on 2 Kings 8:8 and following; 2 Kings 13:3.

The Syrians.—Hebrew, hârammîm, instead of ‘Arammîm’ (Kings). So too the Vulgate and Targum. The Syriac, as usual, confuses Aram with Edom. The Septuagint renders “the archers,” as if the word were the participle of râmâh, “to shoot.” Perhaps the chronicler intended ha-rômîm, “the archers.” (Compare 1 Samuel 31:3; Jeremiah 4:29.)
