Leviticus 13:3-4

Good News Translation

³ The priest shall examine the sore, and if the hairs in it have turned white and the sore appears to be deeper than the surrounding skin, it is a dreaded skin disease, and the priest shall pronounce you unclean. ⁴ But if the sore is white and does not appear to be deeper than the skin around it and the hairs have not turned white, the priest shall isolate you for seven days.
