Leviticus 14:21
And if he be poor, and cannot get so much; then he shall take one lamb for a trespass offering to be waved, to make an atonement for him, and one tenth deal of fine flour mingled with oil for a meat offering, and a log of oil; And if he be poor, and cannot get so much; then he shall take one lamb for a trespass offering to be waved, to make an atonement for him, and one tenth deal of fine flour mingled with oil for a meat offering, and a log of oil;
This verse is part of the law of Moses prescribing the offering a person cleansed of leprosy was to bring to the priest. Leprosy made a person ceremonially unclean, the case was examined by the priest, and those judged unclean were isolated from family and society and cut off from the congregation of Israel. The cleansed man was to present to the priest the offering Moses commanded, and the priest's examination and declaration publicly confirmed that he was free from disease and could return to family and community.
The priest was not to accept the offering until he had thoroughly examined the man and publicly proclaimed him entirely free from infectious disease, in sound health, and able to return to family and friends without danger to them. Jesus directed the healed leper to go to the priest and present the offering Moses commanded. The healed man did what he was directed to do.
That direction showed that Jesus' healing and teaching were not opposed to the law of Moses and the Jewish law. It proved false the charge that His teachings were opposed to the law of Moses and exalted Himself. The offering gave the priests and the people testimony of the cure.
It gave the priests testimony of divine power and evidence that could convince those open to conviction. The priest's examination and certification of the cure made the offering and the man's restoration a public testimony to Christ's power and respect for the law. Obedience brought the man to the same priests who had banished him and forced an examination they could not evade, and when he was pronounced clean it produced great excitement among the watching multitude because such a cure had never before been known; it convinced the priests of divine power, though they still refused Him as Messiah. The ceremonial ordinances in this passage were sacred types whose meaning was made clear by Christ's death, when type met antitype.
