14:25 The priest shall put the blood - Upon the extremities of the body, to include the whole. And some of the oil was afterwards put in the same places upon the blood. That blood seems to have been a token of forgiveness, the oil of healing: For God first forgiveth our iniquities, and then healeth our diseases. When the leper was anointed, the oil must have blood under it, to signify that all the graces and comforts of the spirit, all his sanctifying influences are owing to the death of Christ. It is by his blood alone that we are sanctified.
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.
