Kabbalah su II Re 19:78

The black locks of hair hang down the sides, covering the ears. This is, we learned, the meaning of the verse, “Hashem bend your ears and hear” (II Melachim 19:16). We have deduced from this that whoever wishes for the king to bend his ear towards him should curl the king’s hair, that is, aim to adjust the judgments deriving from the hairs on the head of Zeir Anpin and pull back the hair from over the ears so it will not hinder the hearing of prayer. Then the king will listen to all that he requires.

The ears of Zeir Anpin
The two ears are for hearing good and evil; both are considered as one, as written, “Hashem, bend your ear and hear” (II Melachim 19:16). The innermost ear is traced with curved markings, to slow down the sound as it penetrates the brain, so the brain could notice it and it will not penetrate quickly; for whatever is done quickly is not done with wholesome wisdom.

Hearing applies to the ear, that is, it is Binah that is called hearing. Hearing comprises all brain lobes of Chochmah, Binah and Da’at; because Chochmah is revealed only starting with Binah (as said in section 130). Chochmah is incorporated in it, as written, “Give therefore your servant an understanding (lit. hearing) heart” (I Melachim 3:9). The heart (spelled Lamed Bet) stands for the Lamed Bet (=32) paths of wisdom. Binah is included in it, as said, “Speak, Hashem; for your servant is listening” (I Shmuel 3:9), and “for we understand (lit. hear) it” (II Melachim 18:26). Da’at is included in it, as said, “Hear, O my son, and receive my sayings” (Mishlei 4:10), “and treasure up my commandments with you” (Ibid. 2:1), hear in the sense of know. Thus, everything depends on the ear. It has already been explained that the reason is that the ears are the beginning point of the revelation in the outer part of the head, hence everything is included in it (as said in section 134). The acceptance of prayers and entreaties and the opening of eyes depend on the ear. This is what is meant by, “Hashem bend your ears and hear; open, Hashem, your eyes and see” (II Melachim 19:16). The ear is prepared by bending, which means the ascent of Malchut to Binah, which brings about the opening of the eyes, which are the brain lobes of Chochmah. Thus, everything derives from the ear.
