Cleansing Unhealthiness
13‘Now when the man with the discharge becomes cleansed from his discharge, then he shall count off for himself seven days for his cleansing; he shall then wash his clothes and bathe his body in running water and will become clean. 14Then on the eighth day he shall take for himself two turtledoves or two young doves, and come before the Lord to the doorway of the tent of meeting and give them to the priest; 15and the priest shall offer them, one as a sin offering and the other as a burnt offering. So the priest shall make atonement on his behalf before the Lord because of his discharge.
Leviticus 15:13-16 (NASB)
