Imamat 11:10-11

11:10 But any creatures that do not have both fins and scales, whether in the seas or in the streams, from all the swarming things of the water and from all the living creatures that are in the water, are detestable to you. 11:11 Since they are detestable to you, you must not eat their meat and their carcass you must detest.

Imamat 11:41

11:41 Every swarming thing that swarms on the land is detestable; it must not be eaten.
