Charles Ellicott Commentary 2 Chronicles 28:17

"For again the Edomites had come and smitten Judah, and carried away captives." — 2 Chronicles 28:17 (ASV)

For again. — And moreover.

Smitten Judah. — Smitten in Judah, i.e., inflicted a defeat upon her. After their reduction by Uzziah, the Edomites had probably remained subject to Judah, until Rezin of Syria expelled the Jews from Elath (2 Kings 16:6), and restored it to them. After that event, the disasters of Ahaz seem to have encouraged them to make a raid upon his territory.
