Leviticus 15:13-15

¹³And if he that has the issue should be cleansed of his issue, then shall he number to himself seven days for his purification; and he shall wash his garments, and bathe his body in water, and shall be clean.

¹⁴And on the eighth day he shall take to himself two turtle-doves or two young pigeons, and he shall bring them before the Lord to the doors of the tabernacle of witness, and shall give them to the priest.

¹⁵And the priest shall offer them one for a sin-offering, and the other for a whole-burnt-offering; and the priest shall make atonement for him before the Lord for his issue.
