Him that is to be cleansed - Of him that has been cleansed. The significance of the act is similar to that in Leviticus 8:11, Leviticus 8:15.

And of the rest of the oil that is in his hand,.... That was either in the hand of the priest that was cleansing, or in the hand of his fellow priest; such of it as was left after some of it had been sprinkled seven times before the Lord:

shall the priest put upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot; signifying that these parts in the leprous sinner need to be sanctified by the grace of the Spirit of God, comparable to oil, with which all the Lord's people are anointed, and is that unction they receive from the Holy One, their great High Priest; by this the ear is sanctified so as to hear the word, so as to understand it and mix it with faith; and the thumb of the right hand having oil put on that, may signify that the actions of good men are influenced by the Spirit of God, who works in them both to will and to do, and without whose grace they can do nothing in a spiritual manner; and the great toe of the right foot, the instrument of walking, being anointed with the same, may denote that it is through the grace of God saints have their conversation in the world in simplicity and godly sincerity, and as becomes the Gospel of Christ: the oil was to be put:

upon the blood of the trespass offering; that is, upon the place of the blood of it, as in Leviticus 14:28; which is, as the Targum of Jonathan paraphrases it, the place in which he put at first the blood of the trespass offering: for the Jewish writers observe (z), that the log of oil depended on the trespass offering; for if the flood of the trespass offering was not first sprinkled, the sprinkling of the oil was of no avail: this shows that the blood of Christ, is the foundation of men's receiving the grace of the Spirit, and that it is owing to that it is bestowed upon them; the application of his grace follows redemption by the blood of Christ, who gave himself to redeem them from all iniquity, and purify unto himself a peculiar people, zealous of good works; and for whomsoever expiation is made by the blood of Christ, they are sanctified by the Spirit of Christ.

(z) Bartenora in Misn. Zebachim, c. 4. sect. 3.

And of the rest of the oil that is in his hand shall the priest put upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot, upon the blood of the trespass offering:

14:17 Upon the blood - Upon the place where that blood was put.

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.
