19. On the third day and on the seventh the person who is ritually clean is to sprinkle the water on the unclean person. On the seventh day he is to purify the man, who, after washing his clothes and pouring water over himself, becomes ritually clean at sunset.
20. Anyone who has become ritually unclean and does not purify himself remains unclean, because the water for purification has not been thrown over him. He defiles the Lord's Tent and will no longer be considered one of God's people.
21. You are to observe this rule for all time to come. The person who sprinkles the water for purification must also wash his clothes; anyone who touches the water remains ritually unclean until evening.
22. Whatever an unclean person touches is unclean, and anyone else who touches it remains unclean until evening.
