11 To what purpose is the multitude of your sacrifices unto me? saith Jehovah. I am sated with burnt-offerings of rams, and the fat of fed beasts; and in the blood of bullocks, and of lambs, and of he-goats I take no pleasure. 12 When ye come to appear before me, who hath required this from your hand—to tread my courts? 13 Bring no more vain oblations! Incense is an abomination unto me,—new moon and sabbath, the calling of convocations—wickedness and the solemn meeting I cannot bear.

Matthew Henry's Commentary on Isaiah 1:11-13

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.
