잠언 24:4의 Musar

Rekanati comments that the gallery, מסגרת, which was attached to the surface of the Table all around (Exodus 25,25), was so called because it alludes to something סגור, closed, shut away, as implied in the word צפון which David used in Psalms 31,20 for describing the location where G–d stores His abundant good. It includes a reference to the primordial light which remains hidden. As to the four rings of the Table, they were to be fastened לעומת המסגרת, next to the frame, since their purpose was to exert the influence they symbolised on that מסגרת.
