Leviticus 13:55

Young's Literal Translation

⁵⁵ And the priest hath seen [that which hath] the plague after it hath been washed, and lo, the plague hath not changed its aspect, and the plague hath not spread, -- it [is] unclean; with fire thou dost burn it; it [is] a fretting in its back-part or in its front-part.
