Vessels of the Tabernacle
The primary tools of the altar of burnt-offering are made of acacia wood and plated with copper. The altar has a sacrificial-lamb, and next to it the vessels of the altar.
And thou shalt make the altar of shittim wood: five cubits long, and five cubits broad, a foursquare shall the altar be, and three cubits shall be its height. And thou shalt make its horns on its four corners, from itself shall its horns be; and thou shalt overlay it with copper. (Exodus 27:1-2 [Leeser])
The second vessel is the laver. Its dimensions are not recorded in the Biblical text. Therefore the model presents its suggested size.
And the Lord spoke unto Moses, saying, Thou shalt also make a laver of copper, with its foot of copper, to wash withal: and thou shalt set it between the tabernacle of the congregation and the altar, and thou shalt put therein water. (Exodus 30:17-18 [Leeser])
The Tabernacle was built from 20 wooden boards on each side and eight wooden boards across the back.
And thou shalt make the boards for the tabernacle of shittim wood, standing up. Ten cubits shall be the length of each board, and a cubit and a half shall be the breadth of each one board. ... And the boards thou shalt overlay with gold, .... And thou shalt rear up the tabernacle, according to the fashion thereof, which thou hast been shown on the mount. (Exodus 26:15-30 [Leeser])
