Hitherto the prophet had yielded a blind obedience to God, doing what he commanded him, though he possibly knew no other reason for it but because God bade him do so (which is a homage we owe unto God, though to none but him); now God expounds himself what he meant to teach the Jews by this, viz. that he did intend that they should be consumed by the people beyond the river Euphrates, as that girdle was there marred; and he also shows them that their own sins in disobeying his word, and following the imaginations of their own hearts, particularly their idolatry, was what had brought this sore judgment upon them.
