Vayikra 11:9-11

Orthodox Jewish Bible

⁹ These shall ye eat of all that are in the mayim; whatsoever hath fins and scales in the mayim, in the seas, and in the rivers, them shall ye eat.

¹⁰ And all that have not fins and scales in the seas, and in the rivers, of all that swarm in the mayim, and of any nefesh hachayyah which is in the mayim, they shall be sheketz (abomination, detestable) unto you;

¹¹ They shall be even sheketz unto you; ye shall not eat of their basar, but ye shall have their nevelah in sheketz.
