Leviticus 20:24-26

²⁴And I said unto you, Ye shall possess their land, and I will give it unto you to possess it, a land flowing with milk and honey: I am the Eternal your God, who have separated you from the nations.

²⁵Ye shall therefore make a difference between the clean beast and the unclean, and between the unclean fowl and the clean; and ye shall not make your souls abominable by the beast, or by the fowl, or by any manner of thing that creepeth on the ground, which I have separated from you as unclean.

²⁶And ye shall be holy unto me, for I the Lord am holy; and I have separated you from the nations, that ye should be mine.
