אַל־תִּפְנ֤וּ אֶל־הָאֹבֹת֙ וְאֶל־הַיִּדְּעֹנִ֔ים אַל־תְּבַקְשׁ֖וּ לְטָמְאָ֣ה בָהֶ֑ם אֲנִ֖י יְהוָ֥ה אֱלֹהֵיכֶֽם׃
Não vos voltareis para os necromantes, nem para os adivinhos; não os consulteis para serdes contaminados por eles; Eu sou Hashem, vosso Deus.
Mishnah Sanhedrin
He who gives of his seed to Molech is not liable unless he delivers it to Molech and causes it to pass through the fire. If he gave it to Molech but did not cause it to pass through the fire, or he caused it to pass through fire but did not give it to Molech, he incurs no penalty, unless he does both. A Ba’al Ob is the pithom who speaks from his armpit. The Yidde’oni is one who speaks from his mouth. These two are stoned; while he who inquires of them transgresses a formal prohibition.
