Leviticus 14:25
And he shall kill the lamb of the trespass offering, and the priest shall take some of the blood of the trespass offering, and put it upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot:
Leviticus 14:25 is part of the law of Moses prescribing the offering and purification ceremony for a person healed of leprosy. That law, set out in Leviticus 14:1-32, required the healed person to go to the priest and offer for his cleansing those things Moses commanded. The priest had first to thoroughly examine him and proclaim to the people that he was entirely free from the infectious disease and in sound health, and only then could the offering be accepted from his hands. This examination and public declaration certified that he might again safely unite with family and friends and be restored to the congregation without endangering them.
Directing a healed leper to present the offering Moses required showed that the healing work upheld rather than opposed the law of Moses and the Jewish code. Christ in this way upheld the ceremonial law itself by enjoining obedience to its requirement. Presenting the required offering compelled the priests to examine and certify the cure, and that enforced examination and acceptance gave them irrefutable testimony to divine healing power. It served as a testimony to the priests of Christ's power to heal while at the same time evidencing that His work did not oppose the law given through Moses.
The required examination and acceptance of the offering produced great excitement because such a cure of leprosy had never before been known. The cleansing ordinances themselves were shadowy types pointing forward to what would be fulfilled in Christ. His death explains their meaning, and when type met antitype the ceremonial requirements ceased to apply.
