The first case is trespass upon a neighbour's rights in "a matter of deposit;" where a man has entrusted something to another to keep, and he has either sold it or unlawfully used it as if it were his own. The second case takes in all fraud in a "bargain," as when, for example, a man sells goods, or a piece of land, representing them to be better than they really are, or asking a price larger than he knows an article to be really worth. The third instance is called "robbery;" by which we are to understand any act or process, even though it should be under colour of legal forms, by means of which a man may manage unjustly to get possession of the property of his neighbour, without giving him due equivalent therefor. The fourth instance is called "oppression" of his neighbour. The English word contains the same image as the Hebrew word, which is used, for instance, of the unnecessary retention of the wages of the _employé_ by the employer (xix. 13); it may be applied to all cases in which a man takes advantage of another's circumstances to extort from him any thing or any service to which he has no right, or to force upon him something which it is to the poor man's disadvantage to take. The last example of offences to which the law of the guilt-offering applied, is the case in which a man finds something and then denies it to the rightful owner. The reference to false swearing which follows, as appears from ver. 5, refers not merely to lying and perjury concerning this last-named case, but equally to all cases in which a man may lie or swear falsely to the pecuniary damage of his neighbour. It is mentioned not merely as aggravating such sin, but because in swearing touching any matter, a man appeals to God as witness to the truth of his words; so that by swearing in these cases he represents God as a party to his falsehood and injustice.
In all these cases, the prescription is the same as in analogous offences in the holy things of Jehovah. First of all, the guilty man must confess the wrong which he has done (Numb. v. 7), then restitution must be made of all of which he has defrauded his neighbour, together with one-fifth additional. But while this may set him right with man, it has not yet set him right with God. He must bring his guilt-offering unto Jehovah (vv. 6, 7); "a ram without blemish out of the flock, according to the priest's estimation, for a guilt offering, unto the priest: and the priest shall make atonement for him before the Lord, and he shall be forgiven; concerning whatsoever he doeth so as to be guilty thereby."
And this completes the law of the guilt-offering. It was thus prescribed for sins which involve a defrauding or injuring of another in respect to material things, whether God or man, whether knowingly or unwittingly. The law was one and unalterable for all; the condition of pardon was plenary restitution for the wrong done, and the offering of a costly sacrifice, appraised as such by the priest, the earthly representative of God, in the shekel of the sanctuary, "a ram without blemish out of the flock."
There are lessons from this ordinance, so plain that, even in the dim light of those ancient days, the Israelite might discern and understand them. And they are lessons which, because man and his ways are the same as then, and God the same as then, are no less pertinent to all of us to-day.
Thus we are taught by this law that God claims from man, and especially from His own people, certain rights of property, of which He will not allow Himself to be defrauded, even through man's forgetfulness or inadvertence. In a later day Israel was sternly reminded of this in the burning words of Jehovah by the prophet Malachi (iii. 8, 9): "Will a man rob God? yet ye rob me. But ye say, Wherein have we robbed thee? In tithes and offerings. Ye are cursed with the curse; for ye rob me, even this whole nation." Nor has God relaxed His claim in the present dispensation. For the Apostle Paul charges the Corinthian Christians (2 Cor. viii. 7), in the name of the Lord, with regard to their gifts, that as they abounded in other graces, so they should "abound in this grace also." And this is the first lesson brought before us in the law of the guilt-offering. God claims His tithe, His first-fruit, and the fulfilment of all vows. It was a lesson for that time; it is no less a lesson for our time.
