Kabbalah do Hioba 34:2

Balm drips into the ears from the three cranial cavities, Chochmah, Binah and Da’at. The drop is called “brook Kerit” (I Melachim 17:3), referring to cutting off (keritah) the ears. The sound enters that curve in the ear and is absorbed in the river of balm, where it is kept and observed whether it is good or bad. This is the meaning of, “For the ear tries words” (Iyov 34:2). Why is it that “the ear tries words” – because the sound remains in that river of balm in the curve of the ears, instead of entering swiftly. It is therefore tried to see whether it is good or bad, just like “the palate tastes food” (Ibid.). Why is it that “the palate tastes food” – the reason is that the food is detained in the palate and does not enter the body immediately, so the palate would taste and distinguish between sweet and bitter.

In the Secrets of Letters of King Shelomo, he says that the four letters Aleph, Chet, Hei and Ayin were crowned with the four letters Gimel, Yud, Caf and Kof in the palate (as said in Mishpatim, section 532). Therefore, there is an allusion to three columns in the palate as well, as said, “the palate tastes food” (Iyov 34:2) referring to the right column; “Can that which is unsavory be eaten without salt?” (Ibid. 6:6) referring to the left column that we must not enjoy before it unites with the right, like the “unsavory without salt.” The verse, “And the work of righteousness shall be peace” (Yeshayahu 32:17) is the central column that unites and makes peace between the two columns, right and left. “More to be desired are they than gold, even much fine gold; sweeter” (Tehillim 19:11) refers to Malchut that receives the abundance of the three columns that are surely sweet.
