Reference for Makkot 3:14
וְהַקּוֹרֵא קוֹרֵא (שם כח) אִם לֹא תִשְׁמֹר לַעֲשׂוֹת וְגוֹ' וְהִפְלָא ה' אֶת מַכֹּתְךָ וְאֵת מַכּוֹת וְגוֹ', וְחוֹזֵר לִתְחִלַּת הַמִּקְרָא (שם כט) וּשְׁמַרְתֶּם אֶת דִּבְרֵי הַבְּרִית הַזֹּאת וְגוֹ', וְחוֹתֵם (תהלים עח) וְהוּא רַחוּם יְכַפֵּר עָוֹן וְגוֹ', וְחוֹזֵר לִתְחִלַּת הַמִּקְרָא. וְאִם מֵת תַּחַת יָדוֹ, פָּטוּר. הוֹסִיף לוֹ עוֹד רְצוּעָה אַחַת וָמֵת, הֲרֵי זֶה גוֹלֶה עַל יָדוֹ. נִתְקַלְקֵל בֵּין בְּרֶעִי בֵּין בְּמַיִם, פָּטוּר. רַבִּי יְהוּדָה אוֹמֵר, הָאִישׁ בְּרֶעִי וְהָאִשָּׁה בְּמָיִם:
And the reader reads, [it being written (Leviticus 19:20): "bikkoreth tihyeh" — "She shall be subject to the reading (kriah)," it being read over the smitten one: "If you shall not heed to do, etc." The senior judge reads, the second counts, and the third "calls" each stroke. And it is a mitzvah for the reader to complete the reading with the completion of the stripes. Failing to do that, he repeats the reading quickly, to make its ending coincide with the completion of the stripes.] ("The reader reads":) (Deuteronomy 28:58): "If you shall not heed to do … then the L rd will make wondrous your smitings and the smitings, etc.", and he returns to the beginning of the verse. (Ibid. 29:8): "And you shall keep the words of this covenant, etc." And he concludes (Psalms 78:38): "and He, being merciful, will atone for the sin, etc.", and he returns to the beginning of the verse. And if he dies under his hand, he is not liable, [having smitten him by authority]. If he added a lash, [erring in the number], and he died, he is exiled. If he soils himself, whether with excrement or with urine [while being smitten], he is except (from the remaining stripes), [it being written (Deuteronomy 25:3): "and your brother be demeaned before your eyes" — and he is thus demeaned.] R. Yehudah says: A man, with excrement; a woman, [even] with urine, [her shame being greater. The halachah is not in accordance with R. Yehudah.]
