Leviticus 11:9–12
Of all the creatures that live in the water, whether in the seas or in the streams, you may eat anything with fins and scales. / But the following among all the teeming life and creatures in the water are detestable to you: everything in the seas or streams that does not have fins and scales. / They shall be an abomination to you; you must not eat their meat, and you must detest their carcasses.
Deuteronomy 14:9, 10
Of all the creatures that live in the water, you may eat anything with fins and scales, / but you may not eat anything that does not have fins and scales; it is unclean for you.
