Exodus 36:28

26and their forty sockets of silver: two sockets under one board, and two sockets under another board.

27For the far part of the tabernacle westward he made six boards.

28He made two boards for the corners of the tabernacle in the far part.

29They were double beneath, and in the same way they were all the way to its top to one ring. He did this to both of them in the two corners.

30There were eight boards and their sockets of silver, sixteen sockets—under every board two sockets.
