This is the ritual for a leprous disease in a cloth of wool or linen, either in warp or woof, or in anything of skin, to decide whether it is clean or unclean.
But the cloth, warp or woof, or anything of skin from which the disease disappears when you have washed it, shall then be washed a second time, and it shall be clean.
Thus you shall keep the people of Israel separate from their uncleanness, so that they do not die in their uncleanness by defiling my tabernacle that is in their midst.
These are the statutes that the Lord commanded Moses concerning a husband and his wife, and a father and his daughter while she is still young and in her father's house.
