“Listen, heavens, and I will speak, and the earth will hear the sayings of my mouth” (Deuteronomy 32:1). Halakha: A person of Israel who had an earache, what is the ruling; is it permitted to heal it on Shabbat? So the Sages taught: Any case where there is uncertainty regarding a life-threatening situation, [it] overrides Shabbat. This earache, if it is life-threatening, one may cure it on Shabbat.
The Rabbis say: If you seek not to ache in your ears, or in any of your limbs, incline your ear to Torah and you will inherit life. From where is it derived? It is as it is stated: “Incline your ear and go to Me; listen, and your soul will live” (Isaiah 55:3). Rabbi Ḥanina bar Pappa said: Anyone who turns his ear away from hearing Torah, his prayer is rejected, as it is stated: “One who turns his ear away from hearing Torah, even his prayer is an abomination” (Proverbs 28:9).
Rabbi Levi said: The ear, to the body, is like the perforated vessel1A vessel with holes cut into it. is to garments, as many garments can he placed over it, and you place incense beneath them; they are all fumigated. So, there are two hundred and forty-eight limbs in this person; by means of the ear, all of them live, as it is stated: “Listen, and your soul will live.” The Holy One blessed be He said: ‘If you inclined your ear to Torah, when you come to begin stating matters of Torah, everyone becomes silent before you, and listens to your words, just as you inclined your ear to listen to matters of Torah.’
From where do you derive it? It is from Moses our master, as, because he inclined his ear to Torah, when he came to begin stating matters of Torah, the upper worlds and the lower worlds became silent and listened to his words. From where is it derived? It is from what we read regarding the matter: “Listen, heavens, and I will speak, [and the earth will hear the sayings of my mouth].”
