אֵין מַלְכוּת נוֹגַעַת בַּחֲבֶרְתָּהּ כִּמְלוֹא הַנִּימָא

ביטוי (אנגלית)

One kingdom does not touch the other, even by the thickness of a hair

הגדרה (אנגלית)

Each kingdom has its own territory and does not interfere in the affairs of its neighboring kingdom. By extension: each governing body has its own authority and cannot interfere in the authority of another body that has its own powers ('נימה' means 'thread').

(“The rabbis are necessary for us, for they are the foundation of the nation… It is necessary to involve literature with them, and our nation must make use of these two authorities, for they do not touch one another, not even by a hair’s breadth.” — Berdyczewski, Writings, vol. 2, p. 101)
