(19) And the priest shall offer the sin offering.--The other ewe lamb mentioned in Leviticus 14:10 the priest is now to offer as a sin offering, to expiate the sins which the restored leper had committed during his illness, having probably given vent to impatient and unbecoming expressions at his loathsome condition, not as due in consequence of having been in a state of uncleanness. The regulations in Leviticus 5:2-3, refer to cases when through thoughtlessness the unclean person forgot his duty.

Verses 19, 20. - The priest shall offer the sin offering. The sin offering is due, according to the regulation given in chapter Leviticus 5:3, in consequence of the man having been in a state of uncleanness. It is followed by the burnt offering and the meat offering, and then the man is restored to his state of legal cleanness, and of communion with God as well as with his fellows

14:10-32 The cleansed leper was to be presented to the Lord, with his offerings. When God has restored us to enjoy public worship again, after sickness, distance, or otherwise, we should testify our thanksgiving by our diligent use of the liberty. And both we and our offerings must be presented before the Lord, by the Priest that made us clean, even our Lord Jesus. Beside the usual rites of the trespass-offering, some of the blood, and some of the oil, was to be put upon him that was to be cleansed. Wherever the blood of Christ is applied for justification, the oil of the Spirit is applied for sanctification; these two cannot be separated. We have here the gracious provision the law made for poor lepers. The poor are as welcome to God's altar as the rich. But though a meaner sacrifice was accepted from the poor, yet the same ceremony was used for the rich; their souls are as precious, and Christ and his gospel are the same to both. Even for the poor one lamb was necessary. No sinner could be saved, had it not been for the Lamb that was slain, and hath redeemed us to God with his blood.And the priest shall offer the sin offering,.... This was the ewe lamb, according to the rite of every sin offering, as Aben Ezra says; and was typical of Christ, as all such offerings were, who was made sin and a sin offering for his people:

and make an atonement for him that was to be cleansed from his uncleanness; for it seems the atonement was not perfected by the trespass offering and all the preceding rites; but a sin offering was necessary both on account of moral uncleanness, the cause of the leprosy, and of ceremonial uncleanness by it:

and afterward he shall kill the burnt offering; the other he lamb; the burnt offering for the most part following the sin or trespass offering as a gift by way of thankfulness, atonement being made for sin by the other offerings; which also was typical of Christ, as all burnt offerings were.
