20:4כ׳:ד׳
1 א

לא קרב אליה. הַמַּלְאָךְ מְנָעוֹ, כְּמוֹ שֶׁנֶּאֱמַר לֹא נְתַתִּיךָ לִנְגֹּעַ אֵלֶיהָ:

לא קרב אליה HE HAD NOT COME NEAR HER — The Angel prevented him, as it is said (v. 6) “I have not permitted thee to touch her” (cf. Genesis Rabbah 52).

הגוי גם צדיק תהרג. אַף אִם הוּא צַדִּיק תַּהַרְגֶנּוּ, שֶׁמָּא כָךְ דַּרְכְּךָ לְאַבֵּד הָאֻמּוֹת חִנָּם? כָּךְ עָשִׂיתָ לְדוֹר הַמַּבּוּל וּלְדוֹר הַפַּלָּגָה, אַף אֲנִי אוֹמֵר שֶׁהֲרַגְתָּם עַל לֹא דָבָר, כְּמוֹ שֶׁאַתָּה אוֹמֵר לְהָרְגֵנִי:

הגוי גם צדיק תהרוג WILT THOU SLAY ALSO A RIGHTEOUS NATION? — Even though it be righteous will you slay it? Is such perhaps Your usual way— to destroy nations without cause? That is what you did to the generation of the Flood and to the generation of the Dispersal. I may indeed say that you slew them without proper cause, just as you think to kill me without cause (Genesis Rabbah 52:6).
