Isaiah 1:11

“To what purpose [is] the multitude of your sacrifices unto me? saith the Lord, &c.] These people, though they neglected the weightier matters of the law, and the more substantial duties of religion, as did the Scribes and Pharisees in Christ’s time, (<402323>Matthew 23:23) yet were very diligent in the observance of the ceremonial law, and repeated their sacrifices almost without number, on which they placed all their trust and dependence; wherefore, to take off their confidence in these things, the Lord observes to them the unprofitableness of them; they could be of no avail to them, for they could not expiate their sins, or atone for them; and they could not be profitable to God, for he…”

“God does not here absolutely disparage sacrifice, which is as old and universal as sin (Gen 3:21; Gen 4:4), and sin is almost as old as the world; but sacrifice, unaccompanied with obedience of heart and life (Sa1 15:22; Psa 50:9-13; Psa 51:16-19; Hos 6:6). Positive precepts are only means; moral obedience is the end. A foreshadowing of the gospel, when the One real sacrifice was to supersede all the shadowy ones, and "bring in everlasting righteousness" (Psa 40:6-7; Dan 9:24-27; Heb 10:1-14). full--to satiety; weary of burnt offerings--burnt whole, except the blood, which was sprinkled about the altar. fat--not to be eaten by man, but burnt on the altar (Lev 3:4-5, Lev 3:11, Lev 3:17).”

“To what purpose - לי למה lâmâh lı̂y. ‘What is it to me; or what profit or pleasure can I have in them?’ God here replies to an objection which might be urged by the Jews to the representation which had been made of their guilt. The objection would be, that they were strict in the duties of their religion, and that they even abounded in offering victims of sacrifice. God replies in this and the following verses, that all this would be of no use, and would meet with no acceptance, unless it were the offering of the heart. He demanded righteousness; and without that, all external offerings would be vain. The same sentiment often occurs in the Old Testament. Hath Jehovah as great delight in…”

“To me - Who am a spirit, and therefore cannot be satisfied with such carnal oblations, but expect to have your hearts and lives, as well as your bodies and sacrifices, presented unto me. Blood - He mentions the fat and blood, because these were in a peculiar manner reserved for God, to intimate that even the best of their sacrifices were rejected by him. Isaiah 1:12”

“1:11-15 The people had so offended God through their sin that he took no pleasure any more in their sacrifices. The Lord wanted Judah to stop the religious exercises he had commanded them to do rather than to continue them in a manner that was sinful and false (1:13). Ritual is never an acceptable substitute for true godliness.”

“what purpose: Isa 66:3; Sa1 15:22; Psa 50:8, Psa 51:16; Pro 15:8, Pro 21:27; Jer 6:20, Jer 7:21; Amo 5:21; Mic 6:7; Mat 9:13 he goats: Heb. great he-goats Isaiah 1:12”
