Exodus 26:15-17

Darby Translation

¹⁵ And the boards for the tabernacle thou shalt make of acacia-wood, standing up;

¹⁶ ten cubits the length of the board, and a cubit and a half the breadth of one board.

¹⁷ One board shall have two tenons, connected one with the other: thus shalt thou make for all the boards of the tabernacle.
