Bible Verses About Defilement: Not to eat holy things while under

"'Any descendant of Aharon with tzara'at or a discharge is not to eat the holy things until he is clean. Anyone who has touched a person made unclean by a dead body, or who has had a seminal emission,

or who has touched a reptile or insect that can make him unclean, or a man who is unclean for any reason and who can transmit to him his uncleanness -

the person who touches any of these will be unclean until evening and is not to eat the holy things unless he bathes his body in water.
