Levítico 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.

17 Y de lo que quedare del aceite que tiene en su mano, pondrá el sacerdote sobre la ternilla de la oreja derecha del que se purifica, y sobre el pulgar de su mano derecha, y sobre el pulgar de su pie derecho, sobre la sangre de la expiación por la culpa;

18 y lo que quedare del aceite que tiene en su mano, pondrá sobre la cabeza del que se purifica; y así lo reconciliará el sacerdote delante del SEÑOR.

19 Y hará el sacerdote la expiación y purificará al que se ha de purificar de su inmundicia, y después degollará el holocausto.

20 Y hará subir el sacerdote el holocausto y el presente sobre el altar, y así lo reconciliará el sacerdote, y será limpio.

21 Mas si fuere pobre, que no alcanzare su mano a tanto, entonces tomará un cordero para expiación por la culpa para la ofrenda mecida, para reconciliarse, y una décima de flor de harina amasada con aceite para presente, y un log de aceite;
