Leviticus 11:43-47

⁴³And ye shall not defile your souls with any of the reptiles that creep upon the earth, and ye shall not be polluted with them, and ye shall not be unclean by them.

⁴⁴For I am the Lord your God; and ye shall be sanctified, and ye shall be holy, because I the Lord your God am holy; and ye shall not defile your souls with any of the reptiles creeping upon the earth.

⁴⁵For I am the Lord who brought you up out of the land of Egypt to be your God; and ye shall be holy, for I the Lord am holy.

⁴⁶This is the law concerning beasts and birds and every living creature moving in the water, and every living creature creeping on the earth;

⁴⁷to distinguish between the unclean and the clean; and between those that bring forth alive, such as should be eaten, and those that bring forth alive, such as should not be eaten.
