Deuteronomy 17:8

כי יפלא IF THERE BE [A THING] TOO HARD [FOR THEE IN JUDGMENT] — The term פלא always denotes separation and being at a distance; it means here that the matter is apart and is hidden from thee. בין דם לדם [IF THERE IS ANYTHING TOO HARD FOR THEE IN JUDGMENT] BETWEEN BLOOD AND BLOOD — i.e. between the blood of the menstruous woman that may be unclean blood, and blood that may be clean (Niddah 19a; cf. Sifrei Devarim 152:5), בין דין לדין BETWEEN PLEA AND PLEA — i.e. between a verdict of acquittal and a verdict of “guilty”. בין נגע לנגע BETWEEN PLAGUE AND PLAGUE — i.e. between a plague that may be unclean and a plague that may be clean. דברי ריבה BEING THINGS OF STRIFE [WITHIN THY GATES] — i.e. that the scholars of the city (the judges) be of different opinions in that particular matter (cf. Onkelos), the one declaring it unclean, the other clean, the one sentencing, the other acquitting, וקמת ועלית THEN SHALT THOU RISE AND GO UP [UNTO THE PLACE WHICH THE LORD THY GOD SHALL CHOOSE] — This (the phrase “go up”) teaches that the Temple (in the vicinity of which the Sanhedrin sat) was situated higher than all other places in Palestine (Sifrei Devarim 152:15; Sanhedrin 87a). (cf. however, Ibn Ezra on Numbers 16:12.)

כִּ֣י יִפָּלֵא֩ מִמְּךָ֨ דָבָ֜ר לַמִּשְׁפָּ֗ט בֵּֽין־דָּ֨ם ׀ לְדָ֜ם בֵּֽין־דִּ֣ין לְדִ֗ין וּבֵ֥ין נֶ֙גַע֙ לָנֶ֔גַע דִּבְרֵ֥י רִיבֹ֖ת בִּשְׁעָרֶ֑יךָ וְקַמְתָּ֣ וְעָלִ֔יתָ אֶ֨ל־הַמָּק֔וֹם אֲשֶׁ֥ר יִבְחַ֛ר יְהֹוָ֥ה אֱלֹהֶ֖יךָ בּֽוֹ׃

If there arise a matter too hard for thee in judgment, between blood and blood, between plea and plea, and between plague and plague, matters of controversy within thy gates: then shalt thou arise, and go up to the place which the Lord thy God shall choose;
