Números 19:19

19 O puro aspergirá sobre o impuro no terceiro dia e no sétimo dia; deverá purificá-lo no sétimo dia. E a pessoa que era impura lavará as suas roupas, se banhará na água e à tarde ficará pura.

19 The man who is clean is to sprinkle those who are unclean on the third and seventh days, and on the seventh day he is to purify them. Those who are being cleansed must wash their clothes and bathe with water, and that evening they will be clean.
