11 What unto me is the multitude of your sacrifices? saith Jehovah: I have had enough of the burnt-offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he-goats. 12 When ye come to appear before me, who hath required this at your hand, to trample my courts? 13 Bring no more vain oblations; incense is an abomination unto me; new moon and sabbath, the calling of assemblies,—I cannot away with iniquity and the solemn meeting. 14 Your new moons and your appointed feasts my soul hateth; they are a trouble unto me; I am weary of bearing them. 15 And when ye spread forth your hands, I will hide mine eyes from you; yea, when ye make many prayers, I will not hear: your hands are full of blood.

Matthew Henry's Commentary on Isaiah 1:11-15

Commentary on Isaiah 1:10-15

(Read Isaiah 1:10-15)

Judea was desolate, and their cities burned. This awakened them to bring sacrifices and offerings, as if they would bribe God to remove the punishment, and give them leave to go on in their sin. Many who will readily part with their sacrifices, will not be persuaded to part with their sins. They relied on the mere form as a service deserving a reward. The most costly devotions of wicked people, without thorough reformation of heart and life, cannot be acceptable to God. He not only did not accept them, but he abhorred them. All this shows that sin is very hateful to God. If we allow ourselves in secret sin, or forbidden indulgences; if we reject the salvation of Christ, our very prayers will become abomination.
