Kabbalah for Exodus 40:38
כִּי֩ עֲנַ֨ן יְהוָ֤ה עַֽל־הַמִּשְׁכָּן֙ יוֹמָ֔ם וְאֵ֕שׁ תִּהְיֶ֥ה לַ֖יְלָה בּ֑וֹ לְעֵינֵ֥י כָל־בֵּֽית־יִשְׂרָאֵ֖ל בְּכָל־מַסְעֵיהֶֽם׃
For the cloud of the LORD was upon the tabernacle by day, and there was fire therein by night, in the sight of all the house of Israel, throughout all their journeys.—
Zohar
Another explanation: "But there went up a mist from the earth." The Aramaic translation says, "But there went up a cloud from the earth." (This is the Shechina), of which it is written: "For the cloud of Hashem was upon the tabernacle" (Shemot 40:38). And the students of the Torah on earth will be watered by her at that time.
