Leviticus 14:19 Meaning and Commentary

Leviticus 14:19

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.

Leviticus 14:19 In-Context

17 "The priest must put some of the oil that is in his hand on the same places he put the blood of the guilt offering. He must put some on the person's right ear lobe. He must put some on the thumb of his right hand. He must put some on the big toe of his right foot.

18 He must put on his head the rest of the oil that is in his hand. It will pay for the person's sin in my sight.

19 "Then the priest must sacrifice the sin offering. It will pay for the person's sin. He will be made 'clean' after being 'unclean.' After that, the priest will kill the burnt offering.

20 He will offer it on the altar. He will offer it together with the grain offering. It will pay for the person's sin. Then he will be 'clean.'

21 "But suppose he is poor. Suppose he can't afford all of those offerings. Then he must bring one male lamb as a guilt offering. It must be lifted up and waved in front of me to pay for his sin. He must also bring eight cups of fine flour along with the lamb. He must mix the flour with olive oil. It is a grain offering. He must offer it along with five ounces of oil.
