He that turneth away his ear from hearing the law - Many suppose, if they do not know their duty, they shall not be accountable for their transgressions; and therefore avoid every thing that is calculated to enlighten them. They will not read the Bible, lest they should know the will of Good; and they will not attend Divine ordinances for the same reason. But this pretense will avail them nothing; as he that might have known his master's will, but would not, shall be treated as he shall be who did know it, and disobeyed it. Even the prayers of such a person as this are reputed sin before God.

He that turneth away his ear from hearing the law, even his prayer [shall be] (d) abomination.
(d) Because it is not of faith which is grounded on God's word or law which the wicked contemn.

He that turneth away his ear from hearing the law,.... Not merely the moral law, but the word of God in general, and any and every doctrine of it; though the law is to be heard and attended to, what it commands and forbids, its precepts, menaces, and curses: indeed the Spirit of God is not received by the hearing of the law, nor does faith come by that; but by hearing the word of God, particularly the Gospel; which yet then turn away their ears from, and are turned to fables, and choose to hearken to anything rather than that; and, like the deaf adder, stop their ears to the voice of the charmer, charming ever so wisely; the folly and sad effects of which will be seen when too late;
even his prayer shall be abomination; that is, to God; not only his ungodly actions, but even his outward exercises of religion, which carry in them some show of goodness and holiness; and particularly his prayer to God, which in upright persons is the delight of the Lord; yet in such an one it will be abhorred by him; when he is in distress, and shall pray to the Lord, he will not only turn a deaf ear to him, as he has to his law or word, but he will despise and abhor him and his prayer; because he has set at nought his counsel, and despised his reproof, Proverbs 1:24.

The sinner at whose prayers God is angry, is one who obstinately refuses to obey God's commands.

(Compare Proverbs 15:8; Proverbs 21:27).
hearing--that is, obeying. God requires sincere worshippers (Psalm 66:18; John 4:24).

9 He who turneth away his ear not to hear of the law,
Even his prayer is an abomination.
Cf. Proverbs 15:8 and the argument 1-Samuel 15:22. Not only the evil which such an one does, but also the apparent good is an abomination, an abomination to God, and eo ipso also in itself: morally hollow and corrupt; for it is not truth and sincerity, for the whole soul, the whole will of the suppliant, is not present: he is not that for which he gives himself out in his prayer, and does not earnestly seek that which he presents and expresses a wish for in prayer.
