Exodus 36:20-22

Young's Literal Translation

²⁰ And he maketh the boards for the tabernacle of shittim wood, standing up;

²¹ ten cubits [is] the length of the [one] board, and a cubit and a half the breadth of the [one] board;

²² two handles [are] to the one board, joined one unto another; so he hath made for all the boards of the tabernacle.
