11 "What to me is the multitude of your sacrifices? says the Lord; I have had enough of burnt offerings of rams and the fat of fed beasts; I do not delight in the blood of bulls, or of lambs, or of he-goats. 12 "When you come to appear before me, who requires of you this trampling of my courts? 13 Bring no more vain offerings; incense is an abomination to me. New moon and sabbath and the calling of assemblies--I cannot endure iniquity and solemn assembly. 14 Your new moons and your appointed feasts my soul hates; they have become a burden to me, I am weary of bearing them. 15 When you spread forth your hands, I will hide my eyes from you; even though you make many prayers, I will not listen; 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.
