Leviticus 13:2-4

Young's Literal Translation

² `When a man hath in the skin of his flesh a rising, or scab, or bright spot, and it hath become in the skin of his flesh a leprous plague, then he hath been brought in unto Aaron the priest, or unto one of his sons the priests;

³ and the priest hath seen the plague in the skin of the flesh, and the hair in the plague hath turned white, and the appearance of the plague [is] deeper than the skin of his flesh -- it [is] a plague of leprosy, and the priest hath seen him, and hath pronounced him unclean.

⁴ `And if the bright spot is white in the skin of his flesh, and its appearance is not deeper than the skin, and its hair hath not turned white, then hath the priest shut up [him who hath] the plague seven days.
