21 And if he be poor, and cannot get so much; then he shall take one lamb for a trespass offering to be waved, to make an atonement for him, and one tenth deal of fine flour mingled with oil for a meat offering, and a log of oil;   22 And two turtledoves, or two young pigeons, such as he is able to get; and the one shall be a sin offering, and the other a burnt offering.   23 And he shall bring them on the eighth day for his cleansing unto the priest, unto the door of the tabernacle of the congregation, before the LORD.   24 And the priest shall take the lamb of the trespass offering, and the log of oil, and the priest shall wave them for a wave offering before the LORD:   25 And he shall kill the lamb of the trespass offering, and the priest shall take some of the blood of the trespass offering, and put it 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:   26 And the priest shall pour of the oil into the palm of his own left hand:   27 And the priest shall sprinkle with his right finger some of the oil that is in his left hand seven times before the LORD:   28 And the priest shall put of the oil that is in his hand 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 place of the blood of the trespass offering:   29 And the rest of the oil that is in the priest's hand he shall put upon the head of him that is to be cleansed, to make an atonement for him before the LORD.   30 And he shall offer the one of the turtledoves, or of the young pigeons, such as he can get;   31 Even such as he is able to get, the one for a sin offering, and the other for a burnt offering, with the meat offering: and the priest shall make an atonement for him that is to be cleansed before the LORD.   32 This is the law of him in whom is the plague of leprosy, whose hand is not able to get that which pertaineth to his cleansing.

      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. ii. 1.
