²⁹ for any one who doth [any] of all these abominations -- even the persons who are doing [so], have been cut off from the midst of their people;

³⁰ and ye have kept My charge, so as not to do [any] of the abominable statutes which have been done before you, and ye do not defile yourselves with them; I [am] Jehovah your God.'
