You are therefore to distinguish between clean and unclean animals and birds. Do not become contaminated by any animal or bird, or by anything that crawls on the ground; I have set these apart as unclean for you.
KJV
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.
ASV
Ye shall therefore make a distinction between the clean beast and the unclean, and between the unclean fowl and the clean: and ye shall not make your souls abominable by beast, or by bird, or by anything wherewith the ground teemeth, which I have separated from you as unclean.
