כי יהיה ריב. סוֹפָם לִהְיוֹת נִגָּשִׁים אֶל הַמִּשְׁפָּט. אֱמֹר מֵעַתָּה אֵין שָׁלוֹם יוֹצֵא מִתּוֹךְ מְרִיבָה, מִי גָּרַם לְלוֹט לִפְרֹשׁ מִן הַצַּדִּיק? הֱוֵי אוֹמֵר זוֹ מְרִיבָה: כי יהיה ריב IF THERE BE A QUARREL [BETWEEN MEN] they will in the end have to approach the judges (because of a bodily injury inflicted by one on the other, since Scripture goes on to state, “and if the wicked man be worthy of lashes”, a punishment that can only follow, in the case of a quarrel, upon one of the parties receiving a blow). You must thus come to the conclusion that nothing good can come out of a quarrel. Just think: what was it that caused Lot to leave the righteous man (Abraham)? You must admit it was a mere quarrel (cf. Genesis 13:7—11; Sifrei Devarim 286:1).
והרשיעו את הרשע. יָכוֹל כָּל הַמִּתְחַיְּבִין בַּדִּין לוֹקִין, תַּלְמוּד לוֹמַר — והיה אם בן הכות הרשע. פְּעָמִים לוֹקֶה וּפְעָמִים אֵינוֹ לוֹקֶה. וּמִי הוּא הַלּוֹקֶה? לְמֹד מִן הָעִנְיָן, "לֹא תַחְסֹם שׁוֹר בְּדִישׁוֹ" — לָאו שֶׁלֹּא נִתַּק לַעֲשֵׂה (עי' ספרי; מכות י"ג): והרשיעו את הרשע THEY SHALL CONDEMN THE WICKED — One might think that all who are found guilty in a law-suit are punished with lashes; Scripture, however, goes on to state, והיה אם בן הכות הרשע AND IT SHALL BE, IF THE WICKED MAN BE WORTHY TO BE BEATEN, [… THAT THE JUDGE SHALL SMITE HIM] — “if”: you learn, therefore, that sometimes he receives lashes and sometimes he does not receive lashes. Who it is that may be punished with lashes can be learnt from the context: (v. 4) “Thou shalt not muzzle the ox when he treadeth out the corn” — which is לאו שלא נתק לעשה a prohibition which is not attached to a positive command (cf. Sifrei Devarim 286:4; Makkot 13b).
