I.The offences here supposed 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. Judges among the Jews had power to adjure not only the witnesses, as with us, but the person suspected (contrary to a rule of our law, that no man is bound to accuse himself), as appears by the high priest adjuring our Saviour, who thereupon answered, though before he stood silent, Mat 26:63, Mat 26:64. Now (Lev 5:1), If a soul sin (that is, a person, for the soul is the man), if he hear the voice of swearing (that is, if he be adjured to testify what he knows, by an oath of the Lord upon him, Kg1 8:31), if in such a case, for fear of offending one that either has been his friend or may be his enemy, he 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 the lowest hell. He that heareth cursing (that is, that is thus adjured) and betrayeth it not (that is, stifles his evidence, and does not utter it), he is a partner with the sinner, and hateth his own soul; see Pro 29:24. Let all that are called out at any time to bear testimony 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, and not to be dallied with. 2. A man's touching any thing that was ceremonially unclean, Lev 5:2, Lev 5:3. If a man, polluted by such touch, came into the sanctuary inconsiderately, or if he neglected to wash himself according to the law, then he was to look upon himself as under guilt, and must bring his offering. Though his touching the unclean thing contracted only a ceremonial defilement, yet his neglect to wash himself according to the law was such an instance either of carelessness or contempt as contracted a moral guilt. If at first it be hidden from him, yet when he knows it he shall be guilty. Note, As soon as ever God by his Spirit convinces our consciences of any sin or duty we must immediately set in with the conviction, and prosecute it, as those that are not ashamed to own our former mistake. 3. Rash swearing. If a man binds himself by an oath that he will do or not do such a thing, and the performance of his oath afterwards proves either unlawful or impracticable, by which he is discharged from the obligation, yet he must bring an offering to atone for his fully in swearing so rashly, as David that he would kill Nabal. And then it was that he must say before the angel that it was an error, Ecc 5:6. He shall be guilty in one of these (Lev 5:4), guilty if he do not perform his oath, and yet, if the matter of it were evil, guilty if he do. Such wretched dilemmas as these do some men bring themselves into by their own rashness and folly; go which way they will their consciences are wounded, sin stares them in the face, so sadly are they snared in the words of their mouth. A more sad dilemma this is than that of the lepers, "If we sit still, we die; if we stir, we die." Wisdom and watchfulness beforehand would prevent these straits.

II.Now in these cases, 1. The offender must confess his sin and bring his offering (Lev 5:5, Lev 5:6); and the offering was not accepted unless it was accompanied with a penitential confession and a humble prayer for pardon. Observe, The confession must be particular, that he hath sinned in that thing; such was David's confession (Psa 51:4), I have done this evil; and Achan's (Jos 7:20), Thus and thus have I done. Deceit lies in generals; many will own in general they have sinned, for that all must own, so that it is not any particular reproach to them; but that they have sinned in this thing they stand too much upon their honour to acknowledge: but the way to be well assured of pardon, and to be well armed against sin for the future, is to be particular in our penitent confessions. 2. The priest must make atonement for him. As the atonement was not accepted without his repentance, so his repentance would not justify him without the atonement. Thus, in our reconciliation to God, Christ's part and ours are both needful.

He shall confess that he hath sinned - Even restitution was not sufficient without this confession, because a man might make restitution without being much humbled; but the confession of sin has a direct tendency to humble the soul, and hence it is so frequently required in the Holy Scriptures, as without humiliation there can be no salvation.

And he shall bring his trespass offering unto the Lord, for the sin which he hath sinned,.... To make atonement for it; this was typical of the sacrifice of Christ, whose soul was made an offering for sin, "Asham" a trespass offering, Isa 53:10 where the same word is used as here:

a female from the flock, a lamb, or kid of the goats, for a sin offering; it is generally thought there was a difference between a trespass offering and a sin offering; but it is not easy to say wherein the difference lies; and what has been observed by learned men is not very satisfactory: and certain it is, that the same offering is here called both a trespass offering and a sin offering; and such as were men of substance, and capable of it, were to bring a female lamb or kid; it being for sins of ignorance, a sacrifice of a less value was admitted; yet it must be a lamb, typical of Christ the Lamb of God; and atonement cannot be made, even for sins of ignorance, but by the blood and sacrifice of Christ:

and the priest shall make an atonement for him concerning his sin; that is, by offering his sacrifice for him, which was a type of the atonement made by the precious blood of Christ, as of a lamb without spot and blemish.

he shall bring his trespass offering unto the Lord for his sins which he hath sinned--A trespass offering differed from a sin offering in the following respects: that it was appointed for persons who had either done evil unwittingly, or were in doubt as to their own criminality; or felt themselves in such a special situation as required sacrifices of that kind [BROWN]. The trespass offering appointed in such cases was a female lamb or kid; if unable to make such an offering, he might bring a pair of turtledoves or two young pigeons--the one to be offered for a sin offering, the other for a burnt offering; or if even that was beyond his ability, the law would be satisfied with the tenth part of an ephah of fine flour without oil or frankincense.
