Leviticus 11:10 DBY

⁸  Of their flesh shall ye not eat, and their carcase shall ye not touch: they shall be unclean unto you.

⁹  These shall ye eat of all that are in the waters: whatever hath fins and scales in waters, in seas and in rivers, these shall ye eat;

¹⁰  but all that have not fins and scales in seas and in rivers, of all that swarm in the waters, and of every living soul which is in the waters -- they shall be an abomination unto you.

¹¹  They shall be even an abomination unto you: of their flesh shall ye not eat, and their carcase ye shall have in abomination.

¹²  Whatever in the waters hath no fins and scales, that shall be an abomination unto you.
