John Gill Commentary Leviticus 14:23

"And on the eighth day he shall bring them for his cleansing unto the priest, unto the door of the tent of meeting, before Jehovah:" — Leviticus 14:23 (ASV)

And he shall bring them on the eighth day, for his cleansing ,
&c.] 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 Leviticus 14:11);

and the same rites are enjoined for the cleansing of the poor leper as the rich one, in (Leviticus 14:23–31) , of which see the notes on (Leviticus 14:12–21) , 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.
