Leviticus 11:9-12King James Version (KJV)
9 These shall ye eat of all that are in the waters: whatsoever hath fins and scales in the waters, in the seas, and in the rivers, them shall ye eat.
10 And all that have not fins and scales in the seas, and in the rivers, of all that move in the waters, and of any living thing which is in the waters, they shall be an abomination unto you:
11 They shall be even an abomination unto you; ye shall not eat of their flesh, but ye shall have their carcases in abomination.
12 Whatsoever hath no fins nor scales in the waters, that shall be an abomination unto you.
Leviticus 11:9-12New International Version (NIV)
9 “‘Of all the creatures living in the water of the seas and the streams you may eat any that have fins and scales. 10 But all creatures in the seas or streams that do not have fins and scales—whether among all the swarming things or among all the other living creatures in the water—you are to regard as unclean. 11 And since you are to regard them as unclean, you must not eat their meat; you must regard their carcasses as unclean. 12 Anything living in the water that does not have fins and scales is to be regarded as unclean by you.
