with regard to the one ring, so shall it be to both of them (so shall they both be made); to the two corners shall they be” (i.e., designed for the two hinder corners). The meaning of these words, which are very obscure in some points, can only be the following: the two corner beams at the tack were to consist of two pieces joined together at a right angle, so as to form as double boards one single whole from the bottom to the top. The expressions “from below” and “up to its head” are divided between the two predicates “doubled” (תּאמים) and “whole” (תּמּים), but they belong to both of them. Each of the corner beams was to be double from the bottom to the top, and still to form one whole. There is more difficulty in the words האחת אל־הטּבּעת in Exo 26:24. It is impossible to attach any intelligible meaning to the rendering “to the first ring,” so that even Knobel, who proposed it, has left it unexplained. There is hardly any other way of explaining it, than to take the word אל in the sense of “having regard to a thing,” and to understand the words as meaning, that the corner beams were to form one whole, from the face that each received only one ring, probably at the corner, and not two, viz., one on each side. This one ring was placed half-way up the upright beam in the corner or angle, in such a manner that the central bolt, which stretched along the entire length of the walls (Exo 26:28), might fasten into it from both the side and back.
verses 25-27
Sixteen sockets were to be made for these eight boards, two for each. - Exo 26:26-29. To fasten the boards, that they might not separate from one another, bars of acacia-wood were to be made and covered with gold, five for each of the three sides of the dwelling; and though it is not expressly stated, yet the reference to rings in Exo 26:29 as holders of the bars (לבּריחים בּתּים) is a sufficient indication that they were passed through golden rings fastened into the boards.
verses 28-29
“And the middle bar in the midst of the boards (i.e., at an equal distance from both top and bottom) shall be fastening (מבריח) from one end to the other.” As it thus expressly stated with reference to the middle bar, that it was to fasten, i.e., to reach along the walls from one end to the other, we necessarily conclude, with Rashi and others, that the other four bars on every side were not to reach the whole length of the walls, and may therefore suppose that they were only half as long as the middle one, so that there were only three rows of bars on each wall, the upper and lower
