Leviticus 11:40-42

Amplified Bible

⁴⁰ And whoever eats some of its meat shall wash his clothes, and be unclean until evening; also whoever picks up its carcass shall wash his clothes, and be unclean until the evening.

⁴¹ ‘Now everything that swarms on the ground is detestable; it is not to be eaten. ⁴² 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.
