What does Jeremiah 8:6 mean?

I hearkened and heard, but they spake not aright: no man repenteth him of his wickedness, saying, What have I done? every one turneth to his course, as a horse that rusheth headlong in the battle.

I hearkened and heard, but they spake not aright: no man repented him of his wickedness, saying, What have I done? every one turned to his course, as the horse rusheth into the battle.

I hearkened and heard, but they spake not aright: no man repenteth him of his wickedness, saying, What have I done? every one turneth to his course, as a horse that rusheth headlong in the battle.

I took note and gave ear, but no one said what is right: no man had regret for his evil-doing, saying, What have I done? everyone goes off on his way like a horse rushing to the fight.

I have given attention, yea, I hearken, They do not speak right, No man hath repented of his wickedness, Saying, What have I done? Every one hath turned to his courses, As a horse is rushing into battle.

I attended, and hearkened; no man speaketh what is good, there is none that doth penance for his sin, saying: What have I done? They are all turned to their own course, as a horse rushing to the battle.

I hearkened and heard: they speak not what is right; there is no man who repenteth him of his wickedness, saying, What have I done? Every one turneth to his course, like a horse rushing into the battle.
