الأمثال ٢٨:٩

9 He who turneth away his ear not to hear of the law, Even his prayer is an abomination. Cf. Pro 15:8 and the argument Sa1 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.

Note, 1. It is by the word and prayer that our communion with God is kept up. God speaks to us by his law, and expects we should hear him and heed him; we speak to him by prayer, to which we wait for an answer of peace. How reverent and serious should we be, whenever we are hearing from and speaking to the Lord of glory! 2. If God's word be not regarded by us, our prayers shall not only not be accepted of God, but they shall be an abomination to him, not only our sacrifices, which were ceremonial appointments, but even our prayers, which are moral duties, and which, when they are put up by the upright, are so much his delight. See Isa 1:11, Isa 1:15. The sinner whose prayers God is thus angry at is one who wilfully and obstinately refuses to obey God's commandments, who will not so much as give them the hearing, but causes his ear to decline the law, and refuses when God calls; God will therefore justly refuse him when he calls. See Pro 1:24, Pro 1:28.

28:9 A person who ignores the law shows no fear of the Lord (1:7), the lawgiver. That person’s prayers are hypocritical—why should God listen to them?
