Parshat Korach contains a curious phrase in Moses's admonition to Korach and the resulting consequences:
וְאִם־בְּרִיאָה יִבְרָא יְהֹוָה וּפָצְתָה הָאֲדָמָה אֶת־פִּיהָ וּבָלְעָה אֹתָם וְאֶת־כׇּל־אֲשֶׁר לָהֶם וְיָרְדוּ חַיִּים שְׁאֹלָה וִידַעְתֶּם כִּי נִאֲצוּ הָאֲנָשִׁים הָאֵלֶּה אֶת־יְהֹוָה׃
But if the Lord creates a new thing, and the earth opens her mouth, and swallows them up, with all that appertain to them, and they go down alive into She᾽ol; then you shall understand that these men have provoked the Lord. (Num 16:30 Koren Bible)
...
וַיֵּרְדוּ הֵם וְכׇל־אֲשֶׁר לָהֶם חַיִּים שְׁאֹלָה וַתְּכַס עֲלֵיהֶם הָאָרֶץ וַיֹּאבְדוּ מִתּוֹךְ הַקָּהָל
They, and all that appertained to them, went down alive into She᾽ol, and the earth closed upon them: and they perished from among the congregation. (Num 16:33 Koren Bible)
What does the phrase "descend alive into Sheol" mean in this context? The Hebrew bible depicts Sheol as the destination of the dead, so how exactly does one descend alive into the pit called Sheol?
