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, Lev 14:21, Lev 14:22. 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.

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.

And he shall bring them on the eighth day, for his cleansing,.... Which supposes him to have gone through all the rites and ceremonies of cleansing throughout the seven days, from his first appearance before the priest; such as his being sprinkled with the cedar wood, hyssop, and scarlet, dipped in the blood of the slain bird, mixed with running water; the shaving off of his hair, and washing his flesh and clothes in water; all which being done, on the eighth day he was to bring his lamb for a trespass offering, and one tenth deal of fine flour, for a meat offering, and two turtledoves or two young pigeons, one for a sin offering and the other for a burnt offering:

unto the priest, unto the door of the tabernacle of the congregation before the Lord; where the rich man also and his offerings were presented; See Gill on Lev 14:11; and the same rites are enjoined for the cleansing of the poor leper as the rich one, in Lev 14:23, of which see the notes on Lev 14:12, signifying that they are not exempt from duty, or abridged of any privilege on account of poverty; the persons and services of the people of God being equally acceptable to him, whether rich or poor.

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 (Act 10:34).
