Charles Ellicott Commentary 2 Chronicles 8:3

"And Solomon went to Hamath-zobah, and prevailed against it." — 2 Chronicles 8:3 (ASV)

And Solomon went. — Marched (2 Samuel 12:29).

Hamath-zobah. —That is, Hamath bordering on Zobah (Compare to 1 Chronicles 18:3). Solomon’s conquest of the kingdom of Hamath, which had been on terms of amity with David, is not mentioned in 1 Kings 9; nor indeed anywhere else in the Old Testament. Thenius (on 2 Kings 14:25) supposes that the text describes not a conquest of Hamath itself, but only the annexation of part of its territory; namely, a part of the highly fruitful plain of Cœle-Syria, called by the Arabs Ard-el-Beqâa. This appears to be correct.

Against it. —Or, over it (a late construction, 2 Chronicles 27:5; Daniel 11:5).
