Albert Barnes Commentary 2 Kings 19:13

"Where is the king of Hamath, and the king of Arpad, and the king of the city of Sepharvaim, of Hena, and Ivvah?" — 2 Kings 19:13 (ASV)

Compare 2 Kings 17:24. The reference in 2 Kings 19:12 is to former Assyrian successes, while 2 Kings 19:13 refers to comparatively recent ones.
