Leviticus 14:20
And the priest shall offer the burnt offering and the meat offering upon the altar: and the priest shall make an atonement for him, and he shall be clean. And the priest shall offer the burnt offering and the meat offering upon the altar: and the priest shall make an atonement for him, and he shall be clean.
Leviticus 14:20 belongs to the law for a person cleansed of leprosy, directing the priest to offer the burnt offering and the grain offering upon the altar and to make atonement for him, after which he shall be clean. The prescribed offering also provides public confirmation of the cleansing, allowing the person to return to family and community. The verse states that provision without explaining the meaning of the offerings or of the atonement. Leprosy made a person unclean and brought isolation from family and Israel's congregation, and a priest examined the person's condition.
The priest cannot receive the offering until he has first thoroughly examined the healed person and publicly pronounced him entirely free from infectious disease and in sound health. The resulting declaration of cleanness restores him to family, friends, and the congregation without endangering them. After the priest examined and declared a leper clean, the prescribed burnt offering and grain offering were presented on the altar, and the priest made atonement for him.
In healing a leper, Jesus honored this law by telling him to say nothing to others but to show himself to the same priests who had banished him and to present the offering commanded by Moses. Jesus directed the cleansed man to complete the offering Moses commanded. That presentation was required to be for a testimony to the priests.
That obedience showed that His work respected and agreed with the law of Moses and the Jewish code rather than opposing it. It compelled even unwilling priests to examine the man and declare him clean. It set before the priests and the people public, irrefutable testimony to the cure and to divine healing power.
The required offerings were part of a ceremonial type whose meaning was clarified when Christ's death fulfilled it. His direction to bring them affirmed that law.
