11 What use to me is the number of the offerings which you give me? says the Lord; your burned offerings of sheep, and the best parts of fat cattle, are a weariness to me; I take no pleasure in the blood of oxen, or of lambs, or of he-goats. 12 At whose request do you come before me, making my house unclean with your feet? 13 Give me no more false offerings; the smoke of burning flesh is disgusting to me, so are your new moons and Sabbaths and your holy meetings.
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.
