Leviticus 11:40-43

⁴⁰Whoever eats any of that carcass must wash his clothes and be unclean until evening. Anyone who picks up such a carcass will wash his clothes and be unclean until evening.

⁴¹Every animal that creeps on the ground is to be detested; it must not be eaten.

⁴²Whatever crawls on its belly, and whatever walks on all four legs, or whatever has many feet—all the animals that creep on the ground, these you must not eat, for they are to be detested.

⁴³You must not make yourselves unclean with any living creatures that creep; you must not make yourselves unclean with them, that you should be made impure by them.
