Leviticus 5:2

That soul which shall touch any unclean thing, or carcase, or [that which is] unclean being taken of beasts, or the dead bodies of abominable [reptiles] which are unclean, or carcases of unclean cattle,

Or if a soul touch any unclean thing, whether it be a carcase of an unclean beast, or a carcase of unclean cattle, or the carcase of unclean creeping things, and if it be hidden from him; he also shall be unclean, and guilty.

“‘Or if anyone touches any unclean thing, whether it is the carcass of an unclean animal, or the carcass of unclean livestock, or the carcass of unclean creeping things, and it is hidden from him, and he is unclean, then he shall be guilty.
