Leviticus 13:12

¹⁰and the priest shall look, and, behold, if it is a white spot in the skin, and it has changed the hair to white, and there be some of the sound part of the quick flesh in the sore—

¹¹it is a leprosy waxing old in the skin of the flesh; and the priest shall pronounce him unclean, and shall separate him, because he is unclean.

— Leviticus 13:12 —

¹³then the priest shall look, and, behold, the leprosy has covered all the skin of the flesh; and the priest shall pronounce him clean of the plague, because it has changed all to white, it is clean.

¹⁴But on whatsoever day the quick flesh shall appear on him, he shall be pronounced unclean.
