Leviticus 13:34-36

Living Bible

³⁴ He shall be examined again on the seventh day, and if the spot has not spread, and it appears to be no deeper than the skin, the priest shall pronounce him well, and after washing his clothes, he is free.^{[a] 35} But if, later on, this spot begins to spread, ³⁶ then the priest must examine him again and, without waiting to see if any yellow hair develops, declare him a leper.
