Deuteronomio 14

ma non mangerete di alcuno di quelli che non hanno pinne e squame; considerateli come impuri.

Mas todo lo que no tuviere aleta y escama, no comeréis: inmundo os será.

And whatsoever hath not fins and scales ye may not eat; it is unclean unto you.

You shall not eat whatever doesn’t have fins and scales. It is unclean to you.
