Exodus

¹⁸And he made fifty clasps of brass to couple the tent together, that it might be one. ¹⁹And he made a covering for the tent of rams' skins dyed red, and a covering of sealskins above. ²⁰And he made the boards for the tabernacle of acacia wood, standing up. ²¹Ten cubits was the length of a board, and a cubit and a half the breadth of each board. ²²Each board had two tenons, joined one to another: thus did he make for all the boards of the tabernacle. ²³And he made the boards for the tabernacle; twenty boards for the south side southward: ²⁴and he made forty sockets of silver under the twenty boards; two sockets under one board for its two tenons, and two sockets under another board for its two tenons.
