Deuteronomy 17:9 Halakhah

וּבָאתָ֗ אֶל־הַכֹּהֲנִים֙ הַלְוִיִּ֔ם וְאֶל־הַשֹּׁפֵ֔ט אֲשֶׁ֥ר יִהְיֶ֖ה בַּיָּמִ֣ים הָהֵ֑ם וְדָרַשְׁתָּ֙ וְהִגִּ֣ידוּ לְךָ֔ אֵ֖ת דְּבַ֥ר הַמִּשְׁפָּֽט׃

And thou shall come unto the priests the Levites, and unto the judge that shall be in those days; and thou shalt inquire; and they shall declare unto thee the sentence of judgment.
