Kabbalah sobre Números 11:1

He answers, surely whatever man thinks and considers in his heart, he does not act upon it until pronouncing it with his lips; nor does he mean it. The uttered word cleaves the air and soars up, flying throughout the world and is made into a sound. Winged creatures carry it and raise it to the king, where it penetrates his ear. This is the meaning of, “And Hashem heard the voice of your words” (Devarim 5:25), “and Hashem heard it, and his anger was kindled” (Bemidbar 11:1).

Different orifices derive from the ear’s orifice. They are the orifice of the eye, the orifice of the mouth, the orifice of the nose. The sound that penetrates the orifice of the ear enters, if necessary, the eyes’ orifices from the ear and the eyes shed tears (as said in the Greater Gathering section 222). The sound enters the aperture in the nose, if necessary, and they billow smoke and fire from the sound (as said in section 126). This is the meaning of, “and Hashem heard it, and his anger was kindled; and the fire of Hashem burned among them” (Bemidbar 11:1). If needed, the sound enters the oral orifice, which enunciates words out of the sound. It is all from the sound that penetrates the ears; it enters the whole body, and everything is moved by it. Much depends on this ear. Happy is he who guards his words. It is therefore written, “Keep your tongue from evil, and your lips from speaking guile” (Tehillim 34:14).
