Kabbalah su Giobbe 24:78

Everyone is waiting for this mouth with a tongue speaking great words. The tongue is the central column that unites the two columns that are the two lips with a crowning bright knot, that is, with a knot and union of the lights with the central column. It crowns them and makes them bright; for the tongue that is the central column makes clear the lights in the two columns in the lips and completes them. It is written of this, “His mouth is most sweet” (Shir Hashirim 5:15), surely, after the central column combined them with each other. His mouth is similar to, “the palate tastes food” (Iyov 24:3): after the inclusion of right and left, they become good and flavorful. “…and he is altogether lovely” (Shir Hashirim 5:15) refers to the two columns, left and right, that are called fire and water. Fire and water are beautiful, lovely and well fashioned, that is, they are lovely to behold, since the colors red and white, which are left and right, are joined together, that is, beauty appears only from the blending of white and red together.
