Sanhedrin 108b:2
The Gemara discusses the generation of the flood and frames the punishment as sweeping and universal, with Adam's world being judged by water. It is a key sugya for the nature and scale of the flood in Chazal.
דָּרֵשׁ רָבָא: מַאי דִּכְתִיב ״לַפִּיד בּוּז לְעַשְׁתּוּת שַׁאֲנָן נָכוֹן לְמוֹעֲדֵי רָגֶל״? מְלַמֵּד שֶׁהָיָה נֹחַ הַצַּדִּיק מוֹכִיחַ אוֹתָם, וְאָמַר לָהֶם דְּבָרִים שֶׁהֵם קָשִׁים כְּלַפִּידִים, וְהָיוּ בּוֹזִים אוֹתוֹ. אָמְרוּ לוֹ: זָקֵן, תֵּיבָה זוֹ לָמָּה? אָמַר לָהֶם: הַקָּדוֹשׁ בָּרוּךְ הוּא מֵבִיא עֲלֵיכֶם אֶת הַמַּבּוּל. אָמְרוּ: מַבּוּל שֶׁל מָה? אִם מַבּוּל שֶׁל אֵשׁ, יֵשׁ לָנוּ דָּבָר אֶחָד וַעֲלִיתָה שְׁמָהּ. וְאִם שֶׁל מַיִם הוּא מֵבִיא, אִם מִן הָאָרֶץ הוּא מֵבִיא, יֵשׁ לָנוּ עֲשָׁשִׁיּוֹת שֶׁל בַּרְזֶל שֶׁאָנוּ מְחַפִּין בָּהֶם אֶת הָאָרֶץ. וְאִם מִן הַשָּׁמַיִם הוּא מֵבִיא, יֵשׁ לָנוּ דָּבָר וְעָקֵב שְׁמוֹ – וְאָמְרִי לַהּ: עִקֵּשׁ שְׁמוֹ. אָמַר לָהֶם: הוּא מֵבִיא מִבֵּין עִקְּבֵי רַגְלֵיכֶם, שֶׁנֶּאֱמַר ״נָכוֹן לְמוֹעֲדֵי רָגֶל״. תַּנְיָא: מֵימֵי הַמַּבּוּל קָשִׁים כְּשִׁכְבַת זֶרַע, שֶׁנֶּאֱמַר ״נָכוֹן לְמוֹעֲדֵי רָגֶל״. אָמַר רַב חִסְדָּא: בְּרוֹתְחִין קִלְקְלוּ בַּעֲבֵירָה, וּבְרוֹתְחִין נִידּוֹנוּ. כְּתִיב הָכָא: ״וַיָּשֹׁכּוּ הַמָּיִם״, וּכְתִיב הָתָם: ״וַחֲמַת הַמֶּלֶךְ שָׁכָכָה״.
Rava taught: What is the meaning of that which is written: “A contemptible torch [lapid] in the thought of him that is at ease, a thing ready for them whose foot slips” (Job 12:5)? This teaches that Noah the righteous would rebuke the people of his generation, and he said to them statements that are harsh as torches [kelapidim], and they would treat him with contempt. They said to him: Old man, why are you building this ark? Noah said to them: The Holy One, Blessed be He, is bringing a flood upon you. They said to him: A flood of what? If it is a flood of fire, we have another item and it is called alita, and it is fireproof. And if it is a flood of water that He brings, if He brings the water from the earth, we have iron plates with which we can plate the earth to prevent the water from rising. And if He brings the water from the heavens, we have an item and it is called ekev, and some say it is called ikkesh, which will absorb the water. Noah said to them: If He wishes He will bring the water from between your feet and you can do nothing to prevent it, as it is stated: “For them whose foot slips.” It is taught in a baraita: The waters of the flood were as hard and thick as semen, as it is stated: “For them whose foot slips”; foot is a euphemism. Rav Ḥisda says: With hot semen they sinned, and with hot water they were punished. As it is written here, at the conclusion of the flood: “And the waters assuaged” (Genesis 8:1), and it is written there: “Then the king’s wrath was assuaged” (Esther 7:10). Just as the term “assuaged” there is referring to the heat of Ahasuerus’s wrath, so too, “assuaged” with regard to the flood is referring to the heat of the waters.
