Leviticus 11:9-11

New Catholic Bible

⁹ “These are the animals that you may eat that live in the water: you may eat anything that has fins and scales in the seas or the rivers. ¹⁰ But all the animals that move through the water, whether seas or rivers, that do not have fins or scales will be considered to be an abomination.

¹¹ “They will be an abomination for you. You shall not eat their meat and you shall consider their carcasses to be an abomination.
