25 “ ‘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.

Read Leviticus 20:25 Using Other Translations

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.
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 ceremonially clean and unclean animals, and between clean and unclean birds. You must not defile yourselves by eating any unclean animal or bird or creature that scurries along the ground. I have identified them as being unclean for you.
