5:14-19 Here are offerings to atone for trespasses against a neighbour. If a man put to his own use unwittingly, any thing dedicated to God, he was to bring this sacrifice. We are to be jealous over ourselves, to ask pardon for the sin, and make satisfaction for the wrong, which we do but suspect ourselves guilty of. The law of God is so very broad, the occasions of sin in this guilty of. The law of God is so very broad, the occasions of sin in this world are so numerous, and we are so prone to evil, that we need to fear always, and to pray always, that we may be kept from sin. Also we should look before us at every step. The true Christian daily pleads guilty before God, and seeks forgiveness through the blood of Christ. And the gospel salvation is so free, that the poorest is not shut out; and so full, that the most burdened conscience may find relief from it. Yet the evil of sin is so displayed as to cause every pardoned sinner to abhor and dread it.

17-19. if a soul sin … though he wist it not, yet is he guilty—This also refers to holy things, and it differs from the preceding in being one of the doubtful cases,—that is, where conscience suspects, though the understanding be in doubt whether criminality or sin has been committed. The Jewish rabbis give, as an example, the case of a person who, knowing that "the fat of the inwards" is not to be eaten, religiously abstained from the use of it; but should a dish happen to have been at table in which he had reason to suspect some portion of that meat was intermingled, and he had, inadvertently, partaken of that unlawful viand, he was bound to bring a ram as a trespass offering [Le 5:16]. These provisions were all designed to impress the conscience with the sense of responsibility to God and keep alive on the hearts of the people a salutary fear of doing any secret wrong.
