Trespassed. — Dealt unfaithfully.
Turned away their faces from the habitation of the Lord. — Comp. Jeremiah 2:27 : “They have turned their backs unto me, and not their faces.” (Comp. also Ezekiel 8:16.)
Turned their backs. — Literally, gave neck (nathan ‘ôreph); a phrase here used as equivalent to turned neck (pânâh ‘ôreph), Jeremiah 2:27, et al. The ordinary meaning is “to put to flight,” as in Psalms 18:41. It is clear from the next verse that the description is meant to apply to Ahaz and his generation.
