Not in Heaven

Not in Heaven (לֹ֥א בַשָּׁמַ֖יִם הִ֑וא, lo ba-shamayim hi) is a phrase found in a Biblical verse,, which encompasses the passage's theme, and takes on additional significance in rabbinic Judaism.

The full verse states: "It is not in heaven, that you should say, 'Who will go up to heaven for us, and get it for us so that we may hear it and observe it?' In general, the verse conforms with how "... the deuteronomic tradition believed its Torah to be an immediately accessible wisdom, neither distant nor wondrous."

Jewish interpretations
The phrase "not in Heaven" is understood to justify human authority to interpret the Torah. The Talmud explains "[The Torah] is not in Heaven" to mean that the meaning of the Torah itself is to be uncovered not by prophets, or even God's miracles or words, but by humankind's interpretation and decision-making. In the story of the Oven of Akhnai, "Rabbi Yehoshua affirmed the independence of human interpretation from divine intervention since this is what God wills. In support he adduces the biblical statement that the Torah is 'not in heaven' ."

In the academic study of Jewish law, the verse "not in Heaven" serves as the Biblical grounding for the jurisprudential structure of halakhah (Jewish law). The source for Rabbinic authority is really from (According to the law which they shall teach you, and according to the judgment which they shall tell you, you shall do). As one author explains, thanks to the midrashic reading of the verse, "...God himself acquiesced in His exclusion from the halakhic process. Having revealed His will in Sinai in the grundnorm, He Himself, according to the Rabbinic explanation, entrusted the interpretation of His will to the Sages."
