הָעוֹשֶׂה אוֹב אוֹ יִדְּעֹנִי בִּרְצוֹנוֹ בְּזָדוֹן חַיָּב כָּרֵת וְאִם הָיוּ שָׁם עֵדִים וְהַתְרָאָה נִסְקָל. הָיָה שׁוֹגֵג מֵבִיא חַטָּאת קְבוּעָה. כֵּיצַד הוּא מַעֲשֵׂה הָאוֹב. זֶה שֶׁהוּא עוֹמֵד וּמַקְטִיר קְטֹרֶת יְדוּעָה וְאוֹחֵז שַׁרְבִיט שֶׁל הֲדַס בְּיָדוֹ וּמְנִיפוֹ וְהוּא מְדַבֵּר בַּלָּאט בִּדְבָרִים יְדוּעִים אֶצְלָם עַד שֶׁיִּשְׁמַע הַשּׁוֹאֵל כְּאִלּוּ אֶחָד מְדַבֵּר עִמּוֹ וּמְשִׁיבוֹ עַל מַה שֶּׁהוּא שׁוֹאֵל בִּדְבָרִים מִתַּחַת הָאָרֶץ בְּקוֹל נָמוּךְ עַד מְאֹד וּכְאִלּוּ אֵינוֹ נִכָּר לָאֹזֶן אֶלָּא בְּמַחֲשָׁבָה מַרְגִּישׁ בּוֹ. וְכֵן הַלּוֹקֵחַ גֻּלְגּלֶת הַמֵּת וּמַקְטִיר לָהּ וּמְנַחֵשׁ בָּהּ עַד שֶׁיִּשָּׁמַע כְּאִלּוּ קוֹל יוֹצֵא מִתַּחַת שֶׁחְיוֹ שָׁפָל עַד מְאֹד וּמְשִׁיבוֹ. כָּל אֵלּוּ מַעֲשֵׂה אוֹב הֵן וְהָעוֹשֶׂה אֶחָד מֵהֶן נִסְקָל:
Anyone who willingly, as a conscious act of defiance, performs the deeds associated with an ov or a yid'oni is liable for karet. If witnesses were present and warned him, he should be stoned to death. If he performed these actions inadvertently, he must bring a fixed sin offering. What do the deeds associated with an ov involve? A person stands up and offers an incense offering of known content. He holds a wand of myrtle in his hand and waves it while whispering a known incantation in a hushed tone. [This continues] until the person making the inquiry hears a voice, as if another person is speaking to him and replying to his questions. It appears as if the words are coming from below the earth in a very low tone, to the extent that it cannot be perceived by the ear, but only sensed by thought. Similarly, among the deeds associated with an ov is taking the skull of a corpse, offering incense, and chanting incantations until one hears a voice in a very low tone emanating from his armpits and replying [to his questions]. Anyone who performs one of these acts should be stoned to death.
