C. F. Keil and Franz Delitzsch on Exodus 26:31-32

Exo 26:31-32

To divide the dwelling into two rooms, a curtain was to be made, of the same material, and woven in the same artistic manner as the inner covering of the walls (Exo 26:1). This was called פּרכת, lit., division, separation, from פּרך to divide, or מסך פּרכת (Exo 35:12; Exo 39:34; Exo 40:21) division of the covering, i.e., to hang this “upon four pillars of gilded acacia-wood and their golden hooks, (standing) upon four silver sockets,” under the loops (קרסים) which held the two halves of the inner covering together (Exo 26:6). Thus the curtain divided the dwelling into two compartments, the one occupying ten cubits and the other twenty of its entire length.
