Leviticus 14:25ESV·traditional attribution

And he shall kill the lamb of the guilt offering. And the priest shall take some of the blood of the guilt offering and put it on the lobe of the right ear of him who is to be cleansed, and on the thumb of his right hand and on the big toe of his right foot.

Matthew Henry Presbyterian @wholebiblehenry

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.

Lev 14:21-32 In 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.
