Jeremiah 8:6

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,.... These are either, the words of the prophet, as Kimchi and Abarbinel think; who listened and attended to, and made his observations upon, the words and actions, conduct and behaviour, of this people, of which he gives an account: or of the Lord himself, as the Targum; who hearkened to the language of their hearts and actions, and heard the words of their mouth; all that they spoke against him, against his prophets, and those that feared his name; all their lying words, their false swearing; all their oaths and curses, and every idle expression that dropped from them; all which he takes notice of, and men are accountable to him for them:

but they spake not aright: what is so in the sight of God and good men; what is agreeable to right reason, and the word of God; they spoke what was contrary to all this. Wicked men neither think aright, nor act aright, nor speak aright.

no man repented him of his wickedness: of his heart, of his lips, and of his life; no man can repent of himself; no man truly does, without the grace of God:

saying, What have I done? which question an impenitent man does not put; but when it is made, the true answer to be returned to it is, that which is contrary to the nature of God; which is a breach of his law; which a man has reason to be ashamed of; at which he may be astonished, it being so exceeding sinful; that which cast the angels out of heaven, Adam out of paradise, and wicked men down to hell; which is deserving of the wrath of God, and eternal death; for which a man can never make atonement himself; and by which he is undone, to all intents and purposes, without an interest in Christ, and salvation by him.

every one turneth to his course: which is not a good, but a bad one; sin is a way, a road, a path, in which men walk; a course, a series of sinning, a progress and persisting in it; such as the course of this world, and this course is evil, Ephesians 2:2:

as the horse rusheth into the battle, which denotes their swiftness to commit sin, the pleasure they take in it, and their inattention to danger, and death by it; see Job 39:21, or overflows {c}; the impetuosity of the horse is expressed by the overflowing of a river.

{c} Pjwv owok "quasi equus ferox", Heb. "inundans", Piscator; "sisut equus effundens se", Schmidt. So Kimchi and Ben Melech interpret it.
