Leviticus 11:1, 4, 41-44

The LORD spoke again to Moses and Aaron, saying to them

Nevertheless, you are not to eat these, among those which chew the cud or divide the hoof: the camel, because it chews the cud but does not divide the hoof; it is [ceremonially] unclean to you.

‘Now everything that swarms on the ground is detestable; it is not to be eaten. Whatever crawls on its belly, and whatever walks on all fours, and whatever has many feet among all things that swarm on the ground, you shall not eat; for they are detestable. Do not make yourselves loathsome (impure, repulsive) by [eating] any swarming thing; you shall not make yourselves unclean by them so as to defile yourselves. For I am the LORD your God; so consecrate yourselves and be holy, for I am holy. You shall not make yourselves unclean with any of the swarming things that swarm or crawls on the ground. [1 Thess 4:7, 8]
