But sacrifice is here presented in a different aspect from elsewhere in the law. In this ceremonial the central thought is not consecration through sacrifice, as in the burnt-offering; nor expiation of guilt through sacrifice, as in the sin-offering; nor yet satisfaction for trespass committed, as in the guilt-offering. It is sacrifice as procuring for the man for whom it is offered purity and life, which is the main thought.

But, according to vv. 52, 53, the atonement is made with both the dead and the living bird. The special thought which is emphasised by the use of the latter, seems to be merely the full completeness of the work of cleansing which has been accomplished through the death of the other bird. For the living bird was represented as ideally identified with the bird which was slain, by being dipped in its blood; and in that it was now loosed from its captivity, this was in token of the fact that the bird, having now given its life to impart cleansing and life to the leper, has fully accomplished that end.

Obviously, this explanation is one that will apply no less readily to the cleansing of the leprous house than of the leprous person. For the leprosy in the house signifies the working of corruption and of decay and death in the wall of the house, in a way adapted to its nature, as really as in the case of the person; and the ceremonial with the birds and other material prescribed means the same with it as with the other,—namely, the removal of the principle of corruption and disease, and impartation of purity and wholesomeness. In both cases the sevenfold sprinkling, as in analogous cases elsewhere in the law, signified the completeness of the cleansing, to which nothing was lacking, and also certified to the leper that by this impartation of new life, and by his cleansing, he was again brought into covenant relations with Jehovah.

With these ceremonies, the leper's cleansing was now in so far effected that he could enter the camp; only he must first cleanse himself and his clothes with water and shave his hair,—ceremonies which, in their primary meaning, are most naturally explained by the importance of an actual physical cleansing in such a case. Every possible precaution must be taken that by no chance he bring the contagion of his late disease into the camp. Of what special importance in this connection, besides the washing, is the shaving of the hair, will be apparent to all who know how peculiarly retentive is the hair of odours and infections of every kind.

The cleansed man might now come into the camp; he is restored to his place as a living Israelite. And yet he may not come to the tabernacle. For even an Israelite might not come, if defiled for the dead; and this is precisely the leper's status at this point. Though delivered from the power of death, there is yet persisting such a connection of his new self with his old leprous self as precludes him from yet entering the more immediate presence of God. The reality of this analogy will appear to any one who compares the rites which now follow (vv. 10-20) with those appointed for the Nazarite, when defiled by the dead (Numb. vi. 9-12).

Seven days, then, as in that case, he remains away from the tabernacle. On the seventh day, he again shaves himself even to the eyebrows, thus ensuring the most absolute cleanness, and washes himself and his clothes in water. The final restoration ceremonial took place on the eighth day,—the day symbolic of the new creation,—when he appeared before Jehovah at the tent of meeting with a he-lamb for a guilt-offering, and another for a sin-offering, and a ewe-lamb for a burnt-offering; also a meal-offering of three tenth-deals, one tenth for each sacrifice, mingled with oil, and a log (3·32 qts.) of oil. The oil was then waved for a wave-offering before the Lord, as also the whole lamb of the guilt-offering (an unusual thing), and then the lamb was slain and offered after the manner of the guilt-offering.

And now followed the most distinctive part of the ceremonial. As in the case of the consecration of the priests was done with the blood of the peace-offering and with the holy oil, so was it done here with the blood of the guilt-offering and with the common oil—now by its waving consecrated to Jehovah—which the cleansed leper had brought. The priest anoints the man's right ear, the thumb of his right hand, and the great toe of his right foot, first with the blood of the guilt-offering, and then with the oil, having previously sprinkled of the oil seven times with his finger before the Lord. The remnant of the oil in the hand of the priest he then pours upon the cleansed leper's head; then offers for him the sin-offering, the burnt-offering, and the meal-offering; and therewith, at last, the atonement is complete, and the man is restored to his full rights and privileges as a living member of the people of the living God.

The chief significance of this ceremonial lies in the prominence given to the guilt-offering. This is evidenced, not only by the special and peculiar use which is made of its blood, in applying it to the leper, but also in the fact that in the case of the poor man, while the other offerings are diminished, there is no diminution allowed as regards the lamb of the guilt-offering, and the log of oil. Why should the guilt-offering have received on this occasion such a place of special prominence? The answer has been rightly given by those who point to the significance of the guilt-offering as representing reparation and satisfaction for loss of service due. By the fact of the man's leprosy, and consequent exclusion from the camp of Israel, God had been, for the whole period of his excision, defrauded, so to speak, of His proper dues from him in respect of service and offerings; and the guilt-offering precisely symbolised satisfaction made for this default in service which he had otherwise been able to render.

Nor is it a fatal objection to this understanding of the matter that, on this principle, he also that for a long time had had an issue should have been required, for his prolonged default of service, to bring a guilt-offering in order to his restoration; whereas from him no such demand was made. For the need, before the law, for the guilt-offering lay, not in the duration of the leprosy, as such apprehend it, but in the nature of the leprosy, as being, unlike any other visitation, in a peculiar sense, a death in life. Even when the man with an issue was debarred from the sanctuary, he was not, like the leper, regarded by the law as a dead man; but was still counted among them that were living in Israel. And if precluded for an indefinite time from the service and worship of God at the tabernacle, he yet, by his public submission to the demands of the law, in the presence of all, rendered still to God the honour due from a member of the living Israel. But in that the leper, unlike any other defiled person, was reckoned ceremonially dead, obviously consistency in the symbolism made it impossible to regard him as having in any sense rendered honour or service to God so long as he continued a leper, any more than if he had been dead and buried. Therefore he must bring a guilt-offering, as one who had, however unavoidably, committed "a trespass in the holy things of the Lord." And so this guilt-offering, in the case of the leper, as in all others, represented the satisfaction of debt; and as the reality or the amount of a debt cannot be affected by the poverty of the debtor, the offering which symbolised satisfaction for the debt must be the same for the poor leper as for the rich leper.
