1:15 And when ye spread forth your hands, I will hide my eyes from you: yea, when ye make many prayers, I will not hear: your hands are full {x} of blood.
(x) He shows that where men are given to evil, deceit, cruelty and extortion, which is meant by blood, there God will show his anger and not accept them though they seem holy, as in Isa 59:3.
1:15 Blood - You are guilty of murder, and oppression.
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.
