Leviticus 20:25-27

Modern English Version

²⁵ You shall therefore make distinction between the clean animal from the unclean, and the unclean fowl from the clean, and you shall not make yourselves detestable by animal, or by fowl, or by any manner of living thing that crawls on the ground, which I have separated from you as unclean. ²⁶ You shall be holy unto Me; for I the Lord am holy and have separated you from other peoples, that you should be Mine.

²⁷ A man or woman who speaks to spirits as a medium or necromancer shall surely be put to death. They shall stone them. Their blood guilt shall be upon them.
