Exodus 36:26

23 And he maketh the boards for the tabernacle; twenty boards for the south side southward;

24 and forty sockets of silver he hath made under the twenty boards, two sockets under the one board for its two handles, and two sockets under the other board for its two handles.

25 And for the second side of the tabernacle, for the north side, he hath made twenty boards,

26 and their forty sockets of silver, two sockets under the one board, and two sockets under the other board;

27 and for the sides of the tabernacle, westward, hath he made six boards;

28 and two boards hath he made for the corners of the tabernacle, in the two sides;

29 and they have been twins below, and together they are twins at its head, at the one ring; so he hath done to both of them at the two corners;
