וְאִם בְּרִיאָה יִבְרָא ה’ וּפָצְתָה הָאֲדָמָה אֶת פִּיהָ וּבָלְעָה אֹתָם וְאֶת כָּל אֲשֶׁר לָהֶם וְיָרְדוּ חַיִּים שְׁאֹלָה וִידַעְתֶּם כִּי נִאֲצוּ הָאֲנָשִׁים הָאֵלֶּה אֶת ה’
If Hashem creates a new thing, and the ground opens its mouth and swallows them and all that is theirs, and they go down alive into the pit, then you will know that these men have despised Hashem.
Rashi cites the Talmud in Sanhedrin 110a, that Moshe said, “If G-d created an opening into the earth during the six days of creation, good. If not, let Him create one now.” The Talmud continues beyond Rashi’s citation. Koheles 1:9 says that there’s nothing new under the sun, i.e., G-d doesn’t create new things! The Talmud therefore revises its understanding of Moshe’s request. He said, “If the opening is here, good. If not, please move it here.”
