John Calvin Commentary Leviticus 14:10

"And on the eighth day he shall take two he-lambs without blemish, and one ewe-lamb a year old without blemish, and three tenth parts [of an ephah] of fine flour for a meal-offering, mingled with oil, and one log of oil." — Leviticus 14:10 (ASV)

And on the eighth. Just as infants on the eighth day, after they were cleansed from the uncleanness they had brought from the womb, were grafted into the Church and made members of it, so now the eighth day is prescribed for the restoration of those who, in the cure they have received, are, as it were, born again. For they are accounted dead whom leprosy had banished from the holy congregation. A sacrifice is therefore appointed which may renew the circumcision that had been in some measure effaced.

Now, the meaning of all the things mentioned here is not clear to me, and I would not have my readers be too curious concerning them. Some aspects can probably be accounted for: the right ear, the thumb of the right hand, and the great toe of the right foot were sprinkled with the blood of the offering because the leper was restored to the ordinary habits and customs of life, thus regaining freedom of movement, action, and conversation with others. For in the ear, there is a mutual connection between speaking and hearing.

The head is anointed or cleansed with oil, so that nothing impure might remain in his whole body.¹⁵

God spares the poor and lowly and does not compel them to offer the two lambs, lest they should be burdened beyond their means. From this it appears that sacrifices are not estimated according to their intrinsic value, but according to the pious feeling that disposes each one to offer liberally in proportion to what he has been given.
