קבלה על שמות 40:38

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.
