Exodus 36:33

30 and there have been eight boards; and their sockets of silver [are] sixteen sockets, two sockets under the one board.

31 And he maketh bars of shittim wood, five for the boards of the one side of the tabernacle,

32 and five bars for the boards of the second side of the tabernacle, and five bars for the boards of the tabernacle, for the sides westward;

33 and he maketh the middle bar to enter into the midst of the boards from end to end;

34 and the boards he hath overlaid with gold, and their rings he hath made of gold, places for bars, and he overlayeth the bars with gold.

35 And he maketh the vail of blue, and purple, and scarlet, and twined linen, work of a designer he hath made it, [with] cherubs;

36 and he maketh for it four pillars of shittim [wood], and overlayeth them with gold; their pegs [are] of gold; and he casteth for them four sockets of silver.
