“None of the offspring of Aaron who has tza'arat or has a discharge shall eat of the holy things until he is clean. Whoever touches anything that is unclean by the dead or a man whose seed discharges from him
and anything able to pass through fire is to be put through the fire and will then be clean. It is also to be purified with the water of cleansing. Anything that cannot stand the fire is to be put through the water.
