Leviticus 13:4-5

⁴Soothly if the shining whiteness that is in the skin, neither is lower than the tother flesh, and the hairs be of the former colour, the priest shall enclose him seven days;

⁵and the priest shall behold him in the seventh day, and soothly if the leprosy wax not further, neither passeth the former terms in the flesh, again the priest shall enclose him again seven other days;
