Ezekiel 22:26

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.

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.
