Leviticus 11:8-10

New Catholic Bible

⁸ You shall not eat their meat nor shall you touch their carcasses. They will be considered to be unclean.

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.
