Genesis 18:22

וַיֹּאמֶר יְהוָה זַעֲקַת סְדֹם וַעֲמֹרָה כִּי־רָבָּה וְחַטָּאתָם כִּי כָבְדָה מְאֹֽד

And the LORD said: ‘Verily, the cry of Sodom and Gomorrah is great, and, verily, their sin is exceeding grievous.

אֵֽרֲדָה־נָּא וְאֶרְאֶה הַכְּצַעֲקָתָהּ הַבָּאָה אֵלַי עָשׂוּ כָּלָה וְאִם־לֹא אֵדָֽעָה

I will go down now, and see whether they have done altogether according to the cry of it, which is come unto Me; and if not, I will know.’

וַיִּגַּשׁ אַבְרָהָם וַיֹּאמַר הַאַף תִּסְפֶּה צַדִּיק עִם־רָשָֽׁע

And Abraham drew near, and said: ‘Will You indeed sweep away the righteous with the wicked?

אוּלַי יֵשׁ חֲמִשִּׁים צַדִּיקִם בְּתוֹךְ הָעִיר הַאַף תִּסְפֶּה וְלֹא־תִשָּׂא לַמָּקוֹם לְמַעַן חֲמִשִּׁים הַצַּדִּיקִם אֲשֶׁר בְּקִרְבָּֽהּ

Peradventure there are fifty righteous within the city; wilt Thou indeed sweep away and not forgive the place for the fifty righteous that are therein?
