(3) Or if he touch the uncleanness of man.—The sundry classes of defilement which a human being might contract and impart to others by contact, are set forth in Leviticus 12-15.

When he knoweth of it, then he shall be guilty.—Better, and he knoweth it, and feeleth that he is guilty. That is, he afterwards becomes conscious that he has contracted the defilement, and feels his guilt. (See Leviticus 5:2.)

5:1-13 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.Hid from him - Either through forgetfulness or indifference, so that purification had been neglected. In such a case there had been a guilty negligence, and a sin-offering was required. On the essential connection between impurity and the sin-offering, see Leviticus 12:1.Le 5:2, 3. Touching Any Thing Unclean.

2. if a soul touch any unclean thing—A person who, unknown to himself at the time, came in contact with any thing unclean, and either neglected the requisite ceremonies of purification or engaged in the services of religion while under the taint of ceremonial defilement, might be afterwards convinced that he had committed an offense.

As soon as he knoweth it, he must not delay to make his peace with God. And though it was sin before, though not known, yet the knowledge of it made it worse, and therefore required the more speedy repentance.

He shall be guilty, not only ceremonially by that touch, but morally for his violation and contempt of God’s authority and command.

Or if he touch the uncleanness of man,.... The dead body of a man, or the bone of a dead body, or a grave, or any profluvious or menstruous person:

whatsoever uncleanness it be that a man shall be defiled withal: not morally, but ceremonially:

and it be hid from him; he is not sensible that he has touched any thing ceremonially unclean:

when he knoweth of it, then he shall be guilty: acknowledge his guilt, and offer a sacrifice for it, as after directed.

Or if he touch the uncleanness of man, whatsoever uncleanness it be that a man shall be defiled withal, and it be hid from him; when he knoweth of it, then he shall be guilty.
