The shadow of this cross passes before us in a double way in our chapter; first, in the circumcision of the "man-child," whereby he became enrolled as a member of the Israel of God; and secondly, in the burnt-offering and sin-offering, whereby the mother was restored from every defiling influence, rendered fit once more to approach the sanctuary and to come in contact with holy things. "And when the days of her purifying are fulfilled, for a son or for a daughter, she shall bring a lamb of the first year for a burnt-offering, and a young pigeon or a turtle-dove for a sin-offering, unto the door of the tabernacle of the congregation, unto the priest; who shall offer it before the Lord, and make an atonement for her; and she shall be cleansed from the issue of her blood. This is the law for her that hath born a male or a female." (Ver. 6, 7.) The death of Christ in its two grand aspects is here introduced to our thoughts as the only thing which could possibly meet and perfectly remove the defilement connected with man's natural birth. The burnt-offering presents the death of Christ according to the divine estimate thereof; the sin-offering, on the other hand, presents the death of Christ as bearing upon the sinner's need. "And if she be not able to bring a lamb, then she shall bring two turtles, or two young pigeons; the one for a burnt-offering and the other for a sin-offering; and the priest shall make an atonement for her, and she shall be clean." Nothing but blood-shedding could impart cleanness. The cross is the only remedy for man's infirmity and man's defilement. Wherever that glorious work is apprehended, by faith, there is perfect cleanness enjoyed. Now, the apprehension may be feeble, the faith may be but wavering, the experience may be shallow; but let the reader remember, for his soul's joy and comfort, that it is not the depth of his experience, the stability of his faith, or the strength of his apprehension, but the divine value, the changeless efficacy, of the blood of Jesus. This gives great rest to the heart. The sacrifice of the cross is the same to every member of the Israel of God whatever be his _status_ in the assembly. The tender considerateness of our ever-gracious God is seen in the fact that the blood of a turtle-dove was as efficacious for the poor as the blood of a bullock for the rich. The full value of the atoning work was alike maintained and exhibited in each. Had it not been so, the humble Israelite, if involved in ceremonial defilement, might, as she gazed upon the well-stocked pastures of some wealthy neighbor, exclaim, Alas! what shall I do? how shall I be cleansed? how shall I get back to my place and privilege in the assembly? I have neither flock nor herd: I am poor and needy. But, blessed be God, the case of such an one was fully met. A pigeon or turtle-dove was quite sufficient. The same perfect and beautiful grace shines forth in the case of the leper in chapter xiv.
