Tafsiran Kejadian 2:6: Rashi, Chizkuni, Sforno & Kitzur Ba'al HaTurim

ואד יעלה AND A MIST WENT UP — This has reference to the creation of Adam: viz., He caused the deep to rise and filled the clouds with water to moisten the dust, and man was created. It is like a kneader of bread who first pours in water and afterwards kneads the dough — similarly here: He first watered the ground and afterwards He formed man (Genesis Rabbah 14:1).

ואד, “and a kind of mist;” the letter ו at the beginning off the word אד, appears to be superfluous; there are numerous such apparently superfluous prefixes ו in the Torah. As a result, in order not to have to consider that letter as superfluous, our author suggests that the meaning of the two verses 56 must be understood thus: “all the grasses etc. in the field were in a state of suspense after having been created, as only a kind of mist had been rising from the earth due to the influence of sun and moon, this being only sufficient to provide minimal moisture for these herbs. The section of the verse commencing with: for “G-d had not yet let it rain, nor had there been a human being to till the earth,” interrupts the story in order to provide us with the reason why none of these plants have been reported as growing.

ואד יעלה מן הארץ, on the day they were completed, i.e. at the end of the sixth “day” a vapour rose from the earth equivalent to beneficial dew which irrigated the earth and enabled it to bring forth further vegetation without the help of rain or man’s labour.
