Charles Ellicott Commentary 2 Kings 17:20

"And Jehovah rejected all the seed of Israel, and afflicted them, and delivered them into the hand of spoilers, until he had cast them out of his sight." — 2 Kings 17:20 (ASV)

And the Lord rejected all the seed of Israel. — Thenius prefers the reading of the Septuagint “and rejected the Lord (as in the last clause of 2 Kings 17:19), and the Lord was angry with all the seed of Israel,” etc. It thus becomes plain that the writer goes back to 2 Kings 17:18, after the parenthesis relating to Judah. “Israel” is used in the narrow sense in those verses.

Into the hand of spoilers — e.g., the Syrians (2 Kings 10:32) and the Assyrians (2 Kings 15:19; 2 Kings 15:29; 2 Kings 17:3). The writer probably remembered Judges 2:14.
