Side-ring EXTRA · Definitions of necromancy
Torah Temimah indexes ov/yid’oni primarily on 19:31. On 20:06 the classical sources supply the operational definitions and the death-penalty framework.
English: A ba’al ov is the pitom who speaks from his armpit; a yid’oni is one who speaks with his mouth. These are liable to stoning; one who consults them is under a prohibition (warning).
Definition and punishment distinction
The verse’s “turning to the ovot and yid’onim” is not vague superstition. Chazal fix two concrete practices, assign sekilah to the practitioner, and leave the consulter under azharah.
