Leviticus 22:4–5

“ ‘If a descendant of Aaron has a defiling skin disease or a bodily discharge, he may not eat the sacred offerings until he is cleansed. He will also be unclean if he touches something defiled by a corpse or by anyone who has an emission of semen, or if he touches any crawling thing that makes him unclean, or any person who makes him unclean, whatever the uncleanness may be.

No man of Aaron’s descendants who has a skin disease or a discharge is to eat from the holy offerings until he is clean. Whoever touches anything made unclean by a dead person or by a man who has an emission of semen, or whoever touches any swarming creature that makes him unclean or any person who makes him unclean—whatever his uncleanness—

“If any of Aaron’s descendants has a skin disease or any kind of discharge that makes him ceremonially unclean, he may not eat from the sacred offerings until he has been pronounced clean. He also becomes unclean by touching a corpse, or by having an emission of semen, or by touching a small animal that is unclean, or by touching someone who is ceremonially unclean for any reason.

“ ‘Anyone from Aaron’s offspring, if he is afflicted with a skin disease or a fluid discharge, shall not eat in the sanctuary until he is clean; and the one who touches any unclean person or a man from whom an emission of semen goes out, or a man who touches any swarmer that is unclean for him or who touches a person who is unclean for him due to whatever his uncleanness,

What man soever of the seed of Aaron is a leper, or hath a running issue; he shall not eat of the holy things, until he be clean. And whoso toucheth any thing that is unclean by the dead, or a man whose seed goeth from him; Or whosoever toucheth any creeping thing, whereby he may be made unclean, or a man of whom he may take uncleanness, whatsoever uncleanness he hath;
