Lev Leviticus, chapter Book of Leviticus, chapter 11

These shall you2f eat of all that [are] in the waters: whatsoever has fins and scales in the waters, in the seas, and in the rivers, them shall you2f eat.Deu 14:9

And all that have not fins and scales in the seas, and in the rivers, of all that move in the waters, and of any living thing which [is] in the waters, they [shall be] an abomination unto you:

They shall be even an abomination unto you; you2f shall not eat of their flesh, but you2f shall have their carcasses in abomination.

Whatsoever has no fins nor scales in the waters, that [shall be] an abomination unto you.
