Leviticus 13:54-56

Contemporary English Version

⁵⁴ he will tell you to wash the clothing or leather and put it aside for another seven days, ⁵⁵ after which he will examine it again. If the spot hasn't spread, but is still greenish or reddish, the clothing or leather is unclean and must be burned. ⁵⁶ But if the spot has faded after being washed, he will tear away the spot.
