Jeremiah 8:12

These leaders were not in the least ashamed of their conduct, not even enough to blush. Therefore the Lord would cause them to fall when the rest of the people fell in the coming invasion (cf. Jeremiah 6:12-15).

"Could men reach a stage of apostasy where they would never repent? Yes they could, and Judah had reached that point [cf. Hebrews 6:4-6]." [Note: Thompson, p. 301.]

This passage is a scathing indictment of Judah’s spiritual leaders.
