2. Mose 26:9

Five of these were to be connected (sewed together) by themselves (לבד), and the other six in the same manner; and the sixth piece was to be made double, i.e., folded together, towards the front of the tent, so as to form a kind of gable, as Josephus has also explained the passage (Ant. iii. 6, 4).

Moses here receives instructions, I. Concerning the inner curtains of the tent or tabernacle, and the coupling of those curtains (Exo 26:1-6). II. Concerning the outer curtains which were of goats' hair, to strengthen the former (Exo 26:7-13). III. Concerning the case or cover which was to secure it from the weather (Exo 26:14). IV. Concerning the boards which were to be reared up to support the curtains, with their bars and sockets (v. 15-30). V. The partition between the holy place and the most holy (Exo 26:31-35). VI. The veil for the door (Exo 26:36, Exo 26:37). These particulars, thus largely recorded, seem of little use to us now; yet, having been of great use to Moses and Israel, and God having thought fit to preserve down to us the remembrance of them, we ought not to overlook them. Even the antiquity renders this account venerable.

26:9 The two goat-hair curtains (26:7) totaled 45 feet by 66 feet. The extra 6 feet were equally distributed to hang down over the front and back of the framework.
