And if a soul sin, and hear the voice of swearing, and is a witness, whether he hath seen or {a} known of it; if he do not utter it, then he shall bear his iniquity.

(a) By which it is commanded to bear witness to the truth, and disclose the iniquity of the ungodly.

Wesley's Notes

5:1 And hear - And for that is, as that particle is often used. For this declares in particular what the sin was. Or, namely, that of cursing, or blasphemy, or execration, as the word commonly signifies, and that either against one's neighbour, or against God. This may seem to be principally intended here, because the crime spoken of is of so high a nature, that he who heard it, was obliged to reveal it, and prosecute the guilty. He hath seen - Been present when it was said. Or known - By sufficient information from others. His iniquity - That is, the punishment of it; so that word is oft used, as Gen 19:15, Num 18:1.

Jamieson-Fausset-Brown Bible Commentary

CHAPTER 5

Le 5:1. Trespass Offerings for Concealing Knowledge.

1. if a soul . hear the voice of swearing-or, according to some, "the words of adjuration." A proclamation was issued calling any one who could give information, to come before the court and bear testimony to the guilt of a criminal; and the manner in which witnesses were interrogated in the Jewish courts of justice was not by swearing them directly, but adjuring them by reading the words of an oath: "the voice of swearing." The offense, then, for the expiation of which this law provides, was that of a person who neglected or avoided the opportunity of lodging the information which it was in his power to communicate.

Matthew Henry's Concise Commentary

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.

Matthew Henry's Whole Bible Commentary

Chapter 5

This chapter, and part of the next, concern the trespass-offering. The difference between this and the sin-offering lay not so much in the sacrifices themselves, and the management of them, as in the occasions of the offering of them. They were both intended to make atonement for sin; but the former was more general, this applied to some particular instances. Observe what is here said, I. Concerning the trespass. If a man sin, 1. In concealing his knowledge, when he is adjured (v. 1). 2. In touching an unclean thing (v. 2, 3). 3. In swearing (v. 4). 4. In embezzling the holy things (v. 14-16). 5. In any sin of infirmity (v. 17-19). Some other cases there are, in which these offerings were to be offered (ch. 6:2-4; 14:12; 19:21; Num. 6:12). II. Concerning the trespass-offerings, 1. Of the flock (v. 5, 6). 2. Of fowls (v. 7-10). 3. Of flour (v. 11-13; but chiefly a ram without blemish (v. 15, etc.).

Verses 1-6

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, Mt. 26:63, 64. Now (v. 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, 1 Ki. 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 Prov. 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, v. 2, 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, Eccl. 5:6. He shall be guilty in one of these (ch. 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 (v. 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 (Ps. 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.
