Kabbalah su I Re 17:3

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.
