Leviticus 20:25-26

21st Century King James Version

²⁵ 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.

²⁶ And ye shall be holy unto Me; for I the Lord am holy and have severed you from other people, that ye should be Mine.
