Verse 1-13 — The offences here noticed are, 1. A man's concealing the truth, when he was sworn as a witness to speak the truth, the whole truth, and nothing but the truth. If, in such a case, for fear of offending one that has been his friend, or may be his enemy, a man refuses to give evidence, or gives it but in part, he shall bear his iniquity. And that is a heavy burden, which, if some course be not taken to get it removed, will sink a man to hell. Let all that are called at any time to be witnesses, think of this law, and be free and open in their evidence, and take heed of prevaricating. An oath of the Lord is a sacred thing, not to be trifled with. 2. A man's touching any thing that was ceremonially unclean. Though his touching the unclean thing only made him ceremonially defiled, yet neglecting to wash himself according to the law, was either carelessness or contempt, and contracted moral guilt. As soon as God, by his Spirit, convinces our consciences of any sin or duty, we must follow the conviction, as not ashamed to own our former mistake. 3. Rash swearing, that a man will do or not do such a thing. As if the performance of his oath afterward prove unlawful, or what cannot be done. Wisdom and watchfulness beforehand would prevent these difficulties. In these cases the offender must confess his sin, and bring his offering; but the offering was not accepted, unless accompanied with confession and humble prayer for pardon. The confession must be particular; that he hath sinned in that thing. Deceit lies in generals; many will own they have sinned, for that all must own; but their sins in any one particular they are unwilling to allow. The way to be assured of pardon, and armed against sin for the future, is to confess the exact truth. If any were very poor, they might bring some flour, and that should be accepted. Thus the expense of the sin-offering was brought lower than any other, to teach that no man's poverty shall ever bar the way of his pardon. If the sinner brought two doves, one was to be offered for a sin-offering, and the other for a burnt-offering. We must first see that our peace be made with God, and then we may expect that our services for his glory will be accepted by him. To show the loathsomeness of sin, the flour, when offered, must not be made grateful to the taste by oil, or to the smell by frankincense. God, by these sacrifices, spoke comfort to those who had offended, that they might not despair, nor pine away in their sins. Likewise caution not to offend any more, remembering how expensive and troublesome it was to make atonement.
Verse 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.
