Leviticus 15:3-7

³This shall be his uncleanness in his discharge: whether his body runs with his discharge, or his body has stopped from his discharge, it is his uncleanness.

⁴“‘Every bed on which he who has the discharge lies shall be unclean; and everything he sits on shall be unclean.

⁵Whoever touches his bed shall wash his clothes, and bathe himself in water, and be unclean until the evening.

⁶He who sits on anything on which the man who has the discharge sat shall wash his clothes, and bathe himself in water, and be unclean until the evening.

⁷“‘He who touches the body of him who has the discharge shall wash his clothes, and bathe himself in water, and be unclean until the evening.
