Leviticus 11, "Difference between unclean and clean food".

For I am the KING YHVH (YEHOVAH) your Almighty: 

"You will therefore sanctify yourselves, and you will be holy; for I am Holy: neither will you defile yourselves with any manner of creeping thing that creeps upon the earth. 

For I am the KING Almighty that bringeth you up out of the land of Egypt, to be your Almighty: 

"You will therefore be Holy, for I am holy".  

This is the law of the beasts, and of the fowl, and of every living creature that moveth in the waters, and of every creature that creepeth upon the earth: to make a difference between the unclean and the clean, and between the beast that may be eaten and the beast that may not be eaten.
