Leviticus 5:2

or if anyone touches an unclean thing, whether a carcass of an unclean wild animal or a carcass of unclean livestock or a carcass of unclean swarming things, and it is hidden from him and he has become unclean, and he realizes his guilt;

“ ‘If anyone becomes aware that they are guilty—if they unwittingly touch anything ceremonially unclean (whether the carcass of an unclean animal, wild or domestic, or of any unclean creature that moves along the ground) and they are unaware that they have become unclean, but then they come to realize their guilt;

Or if someone touches anything unclean—a carcass of an unclean wild animal, or unclean livestock, or an unclean swarming creature—without being aware of it, he is unclean and incurs guilt.

“Or suppose you unknowingly touch something that is ceremonially unclean, such as the carcass of an unclean animal. When you realize what you have done, you must admit your defilement and your guilt. This is true whether it is a wild animal, a domestic animal, or an animal that scurries along the ground.

Or if a person touches anything unclean, whether an unclean wild animal’s dead body or an unclean domestic animal’s dead body or an unclean swarmer’s dead body, but he is unaware of it, he is unclean and he is guilty.

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.
