Leviticus 15:4 CPDV

²  Speak to the sons of Israel, and say to them: The man who undergoes a flow of seed shall be unclean.

³  And then he shall be judged subject to this fault, if a filthy fluid, at each moment, adheres to his flesh and gathers there.

⁴  Every bed on which he sleeps shall be unclean, and every place where he sits.

⁵  If any man has touched his couch, he shall wash his clothes, and having washed with water, he shall be unclean until evening.

⁶  If he will have sat where that man has sat, he shall also wash his clothes, and having washed with water, he shall be unclean until evening.
