Leviticus 13:34-36

Revised Standard Version

³⁴ and on the seventh day the priest shall examine the itch, and if the itch has not spread in the skin and it appears to be no deeper than the skin, then the priest shall pronounce him clean; and he shall wash his clothes, and be clean. ³⁵ But if the itch spreads in the skin after his cleansing, ³⁶ then the priest shall examine him, and if the itch has spread in the skin, the priest need not seek for the yellow hair; he is unclean.
