Leviticus 14:24

And the priest shall take the lamb of the trespass offering, and the log of oil, and the priest shall wave them for a wave offering before the LORD:

This law belongs to Moses, requiring a person cleansed of leprosy to bring the prescribed offering to the priest for cleansing. In its immediate setting it describes the purification ceremony in which the priest presents the lamb of the trespass offering and the log of oil as a wave offering before the Lord. That ceremony stands within the broader procedures for a person healed of leprosy set out in Leviticus 14:1-32, where the priest's examination and declaration determines whether the person can return to family and community.

The priest's examination and declaration certifies that the person is free of disease and restores him to family, friends, community, and congregation. The healed man must go to the same priests who had examined him and banished him, show himself to the priest, and present his offering. The priests are not allowed to accept an offering from one who had leprosy unless they first thoroughly examine him and proclaim to the people that he is entirely free from the infectious disease, in sound health, and can again unite with family and friends without endangering them.

In the healing of the leper, the man was directed to follow this law by showing himself to the priest and presenting the offering Moses commanded. That obedience showed that the healing and the teaching upheld the law of Moses and the Jewish code and were not opposed to them. It answered the charge of opposition, including the Pharisees' charge that the teachings were opposed to the law of Moses and meant to exalt self, since special direction was given to obey the law of Moses.

Directing the offering affirmed the authority of that law until its types were fulfilled in death. Presenting the prescribed offering serves as a public testimony to priests and people, convincing the priests of the divine power that healed him and proving respect for the law. When the examination ends in pronouncing the man free and privileged to return to family and friends, great excitement follows among the anxious multitude, for such a thing had never before been known.
