Leviticus 13:54-56

Amplified Bible, Classic Edition

⁵⁴ Then the priest shall command that they wash the thing in which the plague is, and he shall shut it up seven days more.

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.
