Leviticus 20:25-27

²⁵'And ye have made separation between the pure beasts and the unclean, and between the unclean fowl and the pure, and ye do not make yourselves abominable by beast or by fowl, or by anything which creepeth on the ground which I have separated to you for unclean;

²⁶and ye have been holy to Me; for holy am I, Jehovah; and I separate you from the peoples to become Mine.

²⁷'And a man or woman — when there is in them a familiar spirit, or who are wizards — are certainly put to death; with stones they stone them; their blood is on them.'
