Исход 26:17

Every board was to have two ידות (lit., hands or holders) to hold them upright, pegs therefore; and they were to be "bound to one another" (משׁלּב, from שׁלב in Chald. to connect, hence שׁלבּים in Kg1 7:28, the corner plates that hold together the four sides of a chest), not "pegged into one another," but joined together by a fastening dovetailed into the pegs, by which the latter were fastened still more firmly to the boards, and therefore had greater holding power than if each one had been simply sunk into the edge of the board.

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.
