Jerusalem Talmud Sanhedrin 6.5

משנה: בֵּית הַסְּקִילָה הָיָה גָבוֹהַּ שְׁתֵּי קוֹמוֹת וְאֶחָד מִן הָעֵדִים דּוֹחֲפוֹ עַל מָתְנָיו. נֶהְפַּךְ עַל לִבּוֹ הוֹפְכוֹ עַל מָתְנָיו אִם מֵת בָּהּ יָצָא. וְאִם לָאו נוֹטֵל אֶת הָאֶבֶן וְנוֹתְנָהּ עַל לִבּוֹ. אִם מֵת בָּהּ יָצָא וְאִם לָאו הָעֵד הַשֵּׁנִי נוֹטֵל אֶת הָאֶבֶן וְנוֹתְנָהּ עַל לִבּוֹ. אִם מֵת בָּהּ יָצָא וְאִם לָאו רְגִימָתוֹ בְכָל יִשְׂרָאֵל שֶׁנֶּאֱמַר יַד הָעֵדִים תִּהְיֶה בּוֹ בָרִאשׁוֹנָה לַהֲמִיתוֹ וְיַד כָּל הָעָם בָּאַחֲרֹנָה.

MISHNAH: The place of stoning was two man-sizes high; one of the witnesses pushed him at his hips. If he fell on his breast, he turns him around on his back. If he died from this, it is sufficient; otherwise he takes the stone and puts it on his breast. If he died from this, it is sufficient; otherwise the second witness takes the stone and puts it on his breast. If he died from this, it is sufficient; otherwise the stoning is on all of Israel as it is said: The witnesses’ hand shall be first on him to kill him,the hand of the entire people afterwards.

הלכה: כָּל הַנִּסְקָלִין נִתְלִין דִּבְרֵי רִבִּי לִיעֶזֶר כול׳. תַּנֵּי. וְכִמְלוֹא קוֹמָתוֹ שֶׁלְּנוֹפֵל הֲרֵי חֲמִשָּׁה. הָכָא אַתָּ מָר. וְכִמְלוֹא קוֹמַת הַנּוֹפֵל הֲרֵי חֲמִשָּׁה. וּבַבּוֹר שֶׁלַּנְּזָקִין אַתָּ מָר. עַד עֲשָׂרָה טְפָחִים. לֹא דוֹמֶה נוֹפֵל מִדַּעַת לַנּוֹפֵל שֶׁלֹּא מִדַּעַת. רִבִּי יוֹנָתָן בֶּן חֲלִי רִבִּי אֶבְדַּומַי בַּר בְּרַתֵּיהּ דְּרִבִּי טָבִי בְשֵׁם רִבִּי יֹאשִׁיָּה. אִילֵּין דְּחַבְּטִין תּוֹרָא בְּחֵיילֵיהּ אֵין בּוֹ מִשּׁוּם רִיסּוּק אֵיבָרִים. בְּיוֹמוֹי דְּרִבִּי פִינְחָס חַבְּטוּ תּוֹרָא בְּחֵיְילֵיהּ. אֲמַר לוֹן. בְּחַיֵיכוֹן שָׁרוּנֵיהּ. שָׁרוּנֵיהּ וְקוּם וַעֲרַק. אָמַר. בָּרוּךְ שֶׁבָּחַר בַּחֲכָמִים וּבְדִבְרֵיהֶם. דְּאָמְרֵי. אִילֵּין דְּחַבְּטִין תּוֹרָא בְּחֵיְילֵיהּ אֵין בּו מִשּׁוּם רִיסּוּק אֵיבָרִים.

HALAKHAH: “All those stoned are hanged, the words of Rebbi Eliezer,” etc. It was stated: “Adding his own height, these are five.” Here you say, adding his own height, these are five. But for a pit in matters of damages, you say even ten handbreadths. One cannot compare one who falls consciously, and one who falls accidentally. Rebbi Jonathan ben Ḥali, Rebbi Eudaimon the son of Rebbi Tabi’s daughter, in the name of Rebbi Josia: Those who throw down an ox with all their might do not cause any of its limbs to break. In the days of Rebbi Phineas they threw down an ox with all their might. He told them, By yourlives, free it. They freed it, it got up and fled. He said, praised be He Who selected the Sages and their pronouncements, for they say, those who throw down an ox with all their might not cause any of its limbs to break.

וּמְנַיִין שֶׁטָּעוּן סְקִילָה. שֶׁנֶּאֱמַר סָקוֹל יִסָּקֵל. וּמְנַיִין שֶׁטָּעוּן דְּחִיָיה. שֶׁנֶּאֱמַר יָרֹה יִיָּרֶה. וּמְנַיִין שֶׁטָּעוּן שְׁתֵּי דְּחִיּוֹת. תַּלְמוּד לוֹמַר יִיָּרֶה.

From where that he needs to be stoned? For it is said, by stoning he be stoned. From where that he needs to be pushed? For it is said, by pushing he be pushed. From where that he needs two pushings? The verse says, to be pushed.
