Kabbalah do Hioba 40:15

The verse: "And fruit tree yielding fruit" (Gen. 1:11) alludes to two grades: one grade above another, which represents male and female. This means that the fruit tree is the Female principle of Zeir Anpin; "yielding fruit" alludes to Yesod of Zeir Anpin, which is male. It is said to be "yielding fruit" because all the fruit that the female yields reaches her from the male. Just as the "fruit tree," which is the Female principle, reveals the potential power that it received from the "fruit tree yielding fruit," which is the male, so it reveals her own potential as well. What is revealed from the potential of the Female principle herself? The Cherubs and pillars are revealed from her own aspect. What are these pillars? They are those that rise up in the smoke of the sacrifice and become stronger because of the offering. They are called "columns of smoke." This is the secret of the verse: "Who is this coming out of the wilderness like columns of smoke" (Song of Songs 3:6). So the Cherubs are the secret of the "herb" that she receives from the male and the "columns of smoke" are the "grass." The Cherubs and pillars exist for "the service of men," but not the "grass," which is meant for food, as it is written: "Behold now animals (Heb. בְּהֵמוֹת), which I made with you; he eats grass like an ox" (Job 40:15).
