「人的肉皮上若長了癤子，或長了癬，或長了火斑，在他肉皮上成了大痲瘋的災病，就要將他帶到祭司亞倫或亞倫作祭司的一個子孫面前。 祭司要察看肉皮上的災病，若災病處的毛已經變白，災病的現象深於肉上的皮，這便是大痲瘋的災病。祭司要察看他，定他為不潔淨。 利未記 13:2-3
If sores or boils or a skin rash should break out and start spreading on your body, you must be brought to Aaron or to one of the other priests. If the priest discovers that the hair in the infected area has turned white and that the infection seems more than skin deep, he will say, “This is leprosy—you are unclean.” Leviticus 13:2-3
