Sanhedrin6: 1
נִגְמַר הַדִּין, מוֹצִיאִין אוֹתוֹ לְסָקְלוֹ. בֵּית הַסְּקִילָה הָיָה חוּץ לְבֵית דִּין, שֶׁנֶּאֱמַר: ,,הוֹצֵא אֶת הַמְקַלֵּל”. אֶחָד עוֹמֵד עַל פֶּתַח בֵּית דִּין וְהַסּוּדָרִין בְּיָדוֹ, וְאָדָם אֶחָד רוֹכֵב הַסּוּס רָחוֹק מִמֶּנּוּ, כְּדֵי שֶׁיְּהֵא רוֹאֵהוּ. אוֹמֵר אֶחָד ,,יֶשׁ לִי לְלַמֵּד עָלָיו זְכוּת”, הַלָּה מֵנִיף בַּסּוּדָרִין וְהַסּוּס רָץ וּמַעֲמִידוֹ. וַאֲפִלּוּ הוּא אוֹמֵר ,,יֶשׁ לִי לְלַמֵּד עַל עַצְמִי זְכוּת”, מַחֲזִירִין אוֹתוֹ, אֲפִלּוּ אַרְבָּעָה וַחֲמִשָּׁה פְעָמִים, וּבִלְבַד שֶׁיֵּשׁ מַמָּשׁ בִּדְבָרָיו. מָצְאוּ לוֹ זְכוּת, פְּטָרוּהוּ; וְאִם לָאו, יוֹצֵא לִסָּקֵל. וְכָרוֹז יוֹצֵא לְפָנָיו: אִישׁ פְּלוֹנִי בֶּן פְּלוֹנִי יוֹצֵא לִסָּקֵל עַל שֶׁעָבַר עֲבֵרָה פְלוֹנִית, וּפְלוֹנִי וּפְלוֹנִי עֵדָיו. כָּל מִי שֶׁיּוֹדֵעַ לוֹ זְכוּת יָבוֹא וִילַמֵּד עָלָיו.
Once the case has been decided, they take him out to stone him. The stoning place was outside the court [area], as it is stat-ed: Take out the blasphemer. One [man] stands at the courthouse door with flags in his hand, and [another] man sits astride a horse at a distance from him within his sight. [If] someone says, “I have grounds for his acquittal,” that one waves the flags and the horse runs and halts him. Even if he says, “I have grounds for my own acquittal,” they return him, even four or five times, as long as there is substance to his words. [If] they found an argument for his acquittal, they acquit him; if not, he goes out to be stoned. A proclamation goes out before him: So-and-so the son of so-and-so is going out to be stoned be-cause he transgressed such-and-such a prohibition, and so-and-so and so-and-so are his witnesses. Whoever knows any grounds for his acquittal should come forward and present them.
