Albert Barnes Commentary 2 Chronicles 32:1

"After these things, and this faithfulness, Sennacherib king of Assyria came, and entered into Judah, and encamped against the fortified cities, and thought to win them for himself." — 2 Chronicles 32:1 (ASV)

Its establishment - literally, “the faithfulness of it” or, in other words, “after these things had been faithfully accomplished.”

2 Chronicles 32:1–8 forms a passage supplementary to 2 Kings 18:13–16.
