'Fin' in the Bible

" 'These you may eat from all that [are] in the water: any in the water that has a fin and scales, [whether] in the seas or in the streams--such you may eat.

But any that does not have a fin and scales, [whether] in the seas or in the streams, {among} all the water's swarmers among all the living creatures that [are] in the water--they [are] a detestable thing to you.

Any that does not have a fin and scales in the water--it [is] a detestable thing to you.

"You may choose to eat from these creatures in the water: you may eat anything with fin and scale,

but you may not eat anything without fin and scale, since it is unclean to you.
