Leviticus 13:55-57

Amplified Bible, Classic Edition

⁵⁵ And the priest shall examine the diseased article after it has been washed, and if the diseased portion has not changed color, though the disease has not spread, it is unclean; you shall burn it in the fire; it is a rotting or corroding [disease], whether the leprous spot be inside or outside.

⁵⁶ If the priest looks and the diseased portion is less noticeable after it is washed, he shall tear it out of the garment, or the skin (leather), or out of the warp or woof.

⁵⁷ If it appears still in the garment, either in the warp or in the woof, or in anything made of skin, it is spreading; you shall burn the diseased part with fire.
