Jeremiah 6:15

Were they ashamed...? — The Hebrew gives an assertion, not a question — They are brought to shame (as in Jeremiah 2:26), because they have committed abominations. And yet, the prophet adds, “they were not ashamed” (the verb is in a different voice). There was no inward feeling of shame even when they were covered with ignominy and confusion. They had lost the power to blush, and were callous and insensible. This was then, as always, the most hopeless of all states. To “fall among them that fall” was its inevitable sequel.
