Exodus 26:15-26:30
You shall make the planks for the Tabernacle of acacia wood, upright. The length of each plank shall be ten cubits and the width of each plank a cubit and a half. Each plank shall have two tenons, parallel to each other; do the same with all the planks of the Tabernacle. Of the planks of the Tabernacle, make twenty planks on the south side: making forty silver sockets under the twenty planks, two sockets under the one plank for its two tenons and two sockets under each following plank for its two tenons; and for the other side wall of the Tabernacle, on the north side, twenty planks, with their forty silver sockets, two sockets under the one plank and two sockets under each following plank. And for the rear of the Tabernacle, to the west, make six planks; and make two planks for the corners of the Tabernacle at the rear. They shall match at the bottom, and terminate alike at the top inside one ring; thus shall it be with both of them: they shall form the two corners. Thus there shall be eight planks with their sockets of silver: sixteen sockets, two sockets under the first plank, and two sockets under each of the other planks.
You shall make bars of acacia wood: five for the planks of the one side wall of the Tabernacle, five bars for the planks of the other side wall of the Tabernacle, and five bars for the planks of the wall of the Tabernacle at the rear to the west. The center bar halfway up the planks shall run from end to end. Overlay the planks with gold, and make their rings of gold, as holders for the bars; and overlay the bars with gold. Then set up the Tabernacle according to the manner of it that you were shown on the mountain.
