Leviticus 15:20
Any bed she lies on will be unclean; any seat she sits on will be unclean.
When a woman experiences bleeding from her body, this uncleanness from her monthly periods shall last for seven days. Anyone who touches her will remain unclean until evening.
Any clothing or leather that has come into contact with a seminal discharge must be washed, and it will remain unclean until evening.
When a man has a seminal discharge, he must wash his entire body with water, and he will be unclean until evening.
This way, the priest will perform the atonement rite before the Lord for the man’s discharge.
On the eighth day, he must bring two turtledoves or two young pigeons, appear before the Lord at the entrance of the Tent of Meeting, and give them to the priest. The priest shall offer one as a sin offering and the other as a burnt offering.
When a man with a discharge is healed, he must wait seven days for his purification. He must wash his clothes and bathe in running water to become clean.
Any clay pot that the sick man touches must be broken, and any wooden utensil must be rinsed.
All those whom the sick man touches without washing his hands must wash their clothes and take a bath; they will be unclean until evening.
