Exodus

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. ²⁵And for the second side of the tabernacle, on the north side, he made twenty boards, ²⁶and their forty sockets of silver; two sockets under one board, and two sockets under another board. ²⁷And for the hinder part of the tabernacle westward he made six boards. ²⁸And two boards made he for the corners of the tabernacle in the hinder part. ²⁹And they were double beneath, and in like manner they were entire unto the top thereof unto one ring: thus he did to both of them in the two corners.
