17 In the sides of the boards shall be made two mortises, whereby one board may be joined to another board: and after this manner shall all the boards be prepared.
18 Of which twenty shall be in the south side southward.
19 For which thou shalt cast forty sockets of silver, that under every board may be put two sockets at the two corners.
20 In the second side also the tabernacle that looketh to the north, there shall be twenty boards,
21 Having forty sockets of silver, two sockets shall be put under each board.
22 But on the west side of the tabernacle thou shalt make six boards.
23 And again other two which shall be erected in the corners at the back of the tabernacle.
