Jeremiah 2:30

But the Lord’s discipline had not produced repentance (cf. Matthew 23:37; Luke 13:34; Acts 7:52). Even the younger generation refused to learn from their chastening. If this oracle dates from the time of Josiah, as seems probable, the younger generation-of which Jeremiah was a part-would have seen the fruit of King Manasseh’s apostasy, and should have turned from it.

"In the secular realm when a great king visited an erring vassal with some kind of punishment the vassal would come to heel, at least in the normal case. But in the case of Israel the divine visitation in some form of judgment was in vain. The people would not accept correction. Rather, they turned on Yahweh’s representatives and spokesmen, the prophets, and destroyed them [cf. Jeremiah 26:20-23; 2 Kings 21:16; Nehemiah 9:26]." [Note: Thompson, pp. 182-83.]
