Charles Ellicott Commentary 2 Chronicles 28:19

"For Jehovah brought Judah low because of Ahaz king of Israel; for he had dealt wantonly in Judah, and trespassed sore against Jehovah." — 2 Chronicles 28:19 (ASV)

Ahaz king of Israel.—Most commentators see an irony in this expression. But, as has been stated before, the southern kingdom was Israel in the chronicler’s idea, although the kingdom of the Ten Tribes was, politically speaking, as much more important as the cedar of Lebanon was in comparison with the blackthorn growing beside it (2 Chronicles 25:18. See also the notes on 2 Chronicles 12:6 and 2 Chronicles 21:2). (Some Hebrew manuscripts, and all ancient versions, read “Judah.” Other Hebrew manuscripts remark that in seven places “king of Judah” should be read instead of “king of Israel.”)

He made Judah naked.—Rather, he behaved loosely, dealt licentiously in Judah (hiphri’a). The verb is so used here only. (Compare to Exodus 5:4, where it is transitive: “Why loose ye the people from their works?”) (The Septuagint omits this; the Authorized Version follows the Vulgate.)

Transgressed sore.—Done unfaithfulness (1 Chronicles 10:13).
