These words seem to be the language of their enemies triumphing over them, as discerning that their God was provoked against them, and would have no more regard or respect unto them; and that they had misused his prophets, which agreeth with 2 Chronicles 36:16. But others rather think these latter words (if not the former also) are the prophet's words, expressive of the cause of their miseries, viz. the Lord's anger, who had divided them, &c., and the effect of it, their enemies having no regard to the most grave and venerable persons amongst them.
