C. F. Keil and Franz Delitzsch on 2 Kings 17:20

2Ki 17:20 ויּמאס is a continuation of יהוה ויּתאנּף in 2Ki 17:18, but so that what follows also refers to the parenthesis in 2Ki 17:19. “Then the Lord rejected all the seed of Israel,” not merely the ten tribes, but all the nation, and humbled them till He thrust them from His face. מאס differs from מפּניו השׁליך. The latter denotes driving into exile; the former, simply that kind of rejection which consisted in chastisement and deliverance into the hand of plunderers, that is to say, penal judgments by which the Lord sought to lead Israel and Judah to turn to Him and to His commandments, and to preserve them from being driven among the heathen. שׁסים בּיד נתן as in Jdg 2:14.
