Leviticus 13:3-5

Douay-Rheims 1899 American Edition

³ And if he see the leprosy in his skin, and the hair turned white, and the place where the leprosy appears lower than the skin and the rest of the flesh: it is the stroke of the leprosy, and upon his judgment he shall be separated.

⁴ But if there be a shining whiteness in the skin, and not lower than the other flesh, and the hair be of the former colour, the priest shall shut him up seven days.

⁵ And the seventh day he shall look on him: and if the leprosy be grown no farther, and hath not spread itself in the skin, he shall shut him up again other seven days.
