Leviticus 20:25

You shall therefore separate the clean beast from the unclean , and the unclean bird from the clean . You shall not make yourselves detestable by beast or by bird or by anything with which the ground crawls , which I have set apart for you to hold unclean .

“‘You must therefore make a distinction between clean and unclean animals and between unclean and clean birds. Do not defile yourselves by any animal or bird or anything that moves along the ground—those that I have set apart as unclean for you.

Ye shall therefore put difference between clean beasts and unclean, and between unclean fowls and clean : and ye shall not make your souls abominable by beast, or by fowl, or by any manner of living thing that creepeth on the ground, which I have separated from you as unclean.
