Matthew Poole and continuators on Jeremiah 13:10

10 This evil people which refuse to hear my words, which walk in the imagination of their heart, and walk after other gods to serve them, and to worship them shall even be as this girdle, which is good for nothing .

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 an 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 shews them, that their own sins in disobedience to his word, and following the imaginations of their own hearts, particularly their Idolatry was what had brought this sore judgment upon them.
