Levítico 13:6

6 E o sacerdote ao sétimo dia o examinará outra vez; e eis que, se a praga se recolheu, e a praga na pele se não estendeu, então o sacerdote o declarará por limpo: apostema é; e lavará os seus vestidos, e será limpo.

6 And the priest is to see him again on the seventh day; and if the mark is less bright and is not increased on his skin, then let the priest say that he is clean: it is only a skin-mark, and after his clothing has been washed he will be clean.
