Leviticus 15:14-15

BBE(i) 14 And on the eighth day he is to take two doves or two young pigeons and come before the Lord to the door of the Tent of meeting and give them to the priest: 15 And they are to be offered by the priest, one for a sin-offering and one for a burned offering, and the priest will take away his sin before the Lord on account of his flow.
