וָאֵ֡רֶא וְהִנֵּה֩ ר֨וּחַ סְעָרָ֜ה בָּאָ֣ה מִן־הַצָּפ֗וֹן עָנָ֤ן גָּדוֹל֙ וְאֵ֣שׁ מִתְלַקַּ֔חַת וְנֹ֥גַֽהּ ל֖וֹ סָבִ֑יב וּמִ֨תּוֹכָ֔הּ כְּעֵ֥ין הַחַשְׁמַ֖ל מִתּ֥וֹךְ הָאֵֽשׁ׃
Or, je vis soudain un vent de tempête venant du Nord, un grand nuage et un feu tourbillonnant avec un rayonnement tout autour, et au centre, au centre du feu, quelque chose comme le hachmal.
Mishnah Chagigah
They may not expound upon the subject of forbidden relations in the presence of three. Nor the work of creation in the presence of two. Nor [the work of] the chariot in the presence of one, unless he is a sage and understands of his own knowledge. Whoever speculates upon four things, it would have been better had he not come into the world: what is above, what is beneath, what came before, and what came after. And whoever takes no thought for the honor of his creator, it would have been better had he not come into the world.
