Leviticus 13:31-33

New American Standard Bible

³¹ But if the priest looks at the infection of the scale, and indeed, it appears to be no deeper than the skin and there is no black hair in it, then the priest shall ^[a]isolate the person with the scaly infection for seven days. ³² And on the seventh day the priest shall look at the infection, and if the scale has not spread and no yellowish hair has ^[b]grown in it, and the appearance of the scale is no deeper than the skin, ³³ then he shall shave himself, but he shall not shave the scale; and the priest shall ^[c]isolate the person with the scale for seven more days.
