TSK · Leviticus 5:2

or when a person swears an oath, speaking thoughtlessly with his lips, whether to do evil or to do good, with regard to anything which the individual might speak thoughtlessly in an oath, even if he did not realize it, but he himself has later come to know it and is guilty with regard to one of these oaths–

When a person touches anything unclean(whether human uncleanness, or an unclean animal, or an unclean detestable creature) and eats some of the meat of the peace offering sacrifice which belongs to the LORD, that person will be cut off from his people.’”

Carcass Uncleanness“‘By these you defile yourselves; anyone who touches their carcass will be unclean until the evening,

Also the pig is ritually impure to you; though it has divided hooves, it does not chew the cud. You may not eat their meat or even touch their remains.

Leave! Leave! Get out of there! Don’t touch anything unclean! Get out of it! Stay pure, you who carry the LORD’s holy items!

Woe to you! You are like unmarked graves, and people walk over them without realizing it!”
