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.

16 Wash you, make you clean; put away the evil of your doings from before mine eyes; cease to do evil; 17 learn to do well; seek justice, relieve the oppressed, judge the fatherless, plead for the widow.

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.
