Leviticus 11:24-25, 41-45

“You will make yourselves ritually unclean until evening if you touch their carcasses. If you pick up one of their carcasses you must wash your clothes and you’ll be unclean until evening.

“Creatures that crawl on the ground are detestable and not to be eaten. Don’t eat creatures that crawl on the ground, whether on their belly or on all fours or on many feet—they are detestable. Don’t make yourselves unclean or be defiled by them, because I am your GOD. “Make yourselves holy for I am holy. Don’t make yourselves ritually unclean by any creature that crawls on the ground. I am GOD who brought you up out of the land of Egypt. Be holy because I am holy.
