| Clarke's Commentary on the Bible And if he be poor - he shall take one lamb - There could be no cleansing without a sacrifice. On this ground the apostle has properly observed that all things under the law are purged with blood; and that without shedding of blood there is no remission. Even if the person be poor, he must provide one lamb; this could not be dispensed with: - so every soul to whom the word of Divine revelation comes, must bring that Lamb of God which takes away the sin of the world. There is no redemption but in his blood.
Gill's Exposition of the Entire BibleAnd if he be poor, and cannot get so much,.... As three lambs, and three tenth deals of fine flour: then he shall take one lamb for a trespass offering to be waved, to make an atonement for him; one he lamb, and was excused the other he lamb for a burnt offering, and the ewe lamb for a sin offering; but a lamb he must bring, a type of Christ the Lamb of God, for without his blood and sacrifice there is no atonement for rich poor, but for both thereby: and one tenth deal of flour mingled with oil for a meat offering: instead three tenth deals; this abatement in the several kinds of offerings was a great indulgence to the poor, and an instance of God's goodness to them, that they might not be pressed above measure, and yet share the same benefits and advantages as the rich: and a log of oil; here was no abatement in this, nor was there need of any; half a pint of oil, in a country which abounded with it, might be bought for a small price: however, the grace of the Spirit, signified by oil, is to be had freely of Christ, and in as large a quantity by a poor man as by a rich man, and is equally necessary to the one as to the other, who are all one in Christ Jesus; see Galatians 3:28.
Keil and Delitzsch Biblical Commentary on the Old TestamentIn cases of poverty on the part of the person to be consecrated, the burnt-offering and sin-offering were reduced to a pair of turtle-doves or young pigeons, and the meat-offering to a tenth of an ephah of meal and oil; but no diminution was allowed in the trespass-offering as the consecration-offering, since this was the conditio sine qua non of reinstatement in full covenant rights. On account of the importance of all the details of this law, every point is repeated a second time in Leviticus 14:21-32.

Jamieson-Fausset-Brown Bible Commentary21-32. if he be poor, and cannot get so much; then he shall take one lamb-a kind and considerate provision for an extension of the privilege to lepers of the poorer class. The blood of their smaller offering was to be applied in the same process of purification and they were as publicly and completely cleansed as those who brought a costlier offering (Ac 10:34).
Matthew Henry's Concise Commentary14:10-32 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.
Matthew Henry's Whole Bible CommentaryVerses 21-32 We have here the gracious provision which the law made for the cleansing of poor lepers. If they were not able to bring three lambs, and three tenth-deals of flour, they must bring one lamb, and one tenth-deal of flour, and, instead of the other two lambs, two turtle-doves or two young pigeons, v. 21, 22. Here see, 1. That the poverty of the person concerned would not excuse him if he brought no offering at all. Let none think that because they are poor God requires no service from them, since he has considered them, and demands that which it is in the power of the poorest to give. "My son, give me thy heart, and with that the calves of thy lips shall be accepted instead of the calves of the stall." 2. That God expected from those who were poor only according to their ability; his commandments are not grievous, nor does he make us to serve with an offering. The poor are as welcome to God's altar as the rich; and, if there be first a willing mind and an honest heart, two pigeons, when they are the utmost a man is able to get, are as acceptable to God as two lambs; for he requires according to what a man has and not according to what he has not. But it is observable that though a meaner sacrifice was accepted from the poor, yet the very same ceremony was used for them as was for the rich; for their souls are as precious and Christ and his gospel are the same to both. Let not us therefore have the faith of our Lord Jesus Christ with respect of persons, Jam. 2:1. |
