All the things that swarm upon the earth are an abomination; they shall not be eaten. You shall not eat, among all things that swarm upon the earth, anything that crawls on its belly, or anything that walks on fours, or anything that has many legs; for they are an abomination. You shall not draw abomination upon yourselves through anything that swarms; you shall not make yourselves unclean therewith and thus become unclean. For I the LORD am your God: you shall sanctify yourselves and be holy, for I am holy. You shall not make yourselves unclean through any swarming thing that moves upon the earth.
Leviticus 11:41-44
