Leviticus 22:4-6

New Life Version

⁴ None of the children of Aaron who has a bad skin disease or something flowing from his body may eat of the holy gifts until he is clean. If one touches anything that is unclean because of a dead body, or has had his seed come from his sex part, ⁵ or touches anything that is unclean that moves on the ground, or touches any man who makes him unclean, for whatever reason, ⁶ the man who touches any such thing will be unclean until evening. He must not eat of the holy gifts unless he has washed his body in water.
