11 "What makes you think I want all your sacrifices?" says the Lord . "I am sick of your burnt offerings of rams and the fat of fattened cattle. I get no pleasure from the blood of bulls and lambs and goats. 12 When you come to worship me, who asked you to parade through my courts with all your ceremony? 13 Stop bringing me your meaningless gifts; the incense of your offerings disgusts me! As for your celebrations of the new moon and the Sabbath and your special days for fasting- they are all sinful and false. I want no more of your pious meetings. 14 I hate your new moon celebrations and your annual festivals. They are a burden to me. I cannot stand them! 15 When you lift up your hands in prayer, I will not look. Though you offer many prayers, I will not listen, for your hands are covered with the blood of innocent victims.

16 Wash yourselves and be clean! Get your sins out of my sight. Give up your evil ways. 17 Learn to do good. Seek justice. Help the oppressed. Defend the cause of orphans. Fight for the rights of widows.

Matthew Henry's Commentary on Isaiah 1:11-17

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.

Commentary on Isaiah 1:16-20

(Read Isaiah 1:16-20)

Not only feel sorrow for the sin committed, but break off the practice. We must be doing, not stand idle. We must be doing the good the Lord our God requires. It is plain that the sacrifices of the law could not atone, even for outward national crimes. But, blessed be God, there is a Fountain opened, in which sinners of every age and rank may be cleansed. Though our sins have been as scarlet and crimson, a deep dye, a double dye, first in the wool of original corruption, and afterwards in the many threads of actual transgression; though we have often dipped into sin, by many backslidings; yet pardoning mercy will take out the stain, Psalm 51:7. They should have all the happiness and comfort they could desire. Life and death, good and evil, are set before us. O Lord, incline all of us to live to thy glory.
