Exodus 36:20 DBY

¹⁸  And he made fifty clasps of copper to couple the tent, that it might be one.

¹⁹  And he made a covering for the tent [of] rams' skins dyed red, and a covering of badgers' skins above [that].

²⁰  And he made the boards for the tabernacle of acacia-wood, standing up;

²¹  ten cubits the length of the boards, and one cubit and a half the breadth of one board;

²²  two tenons in one board, connected one with the other: thus did he make for all the boards of the tabernacle.
