Leviticus 15:6-8

Amplified Bible

⁶ and whoever sits on anything on which the man with the discharge has been sitting shall wash his clothes and bathe in water, and be unclean until evening. ⁷ Also whoever touches the man with the discharge shall wash his clothes and bathe in water, and be unclean until evening. ⁸ And if he who has the discharge spits on one who is clean, then he shall wash his clothes and bathe in water, and be unclean until evening.
