¹⁵ “And for the tabernacle you shall ^(A)make the boards of acacia wood, standing upright. ¹⁶ Ten cubits shall be the length of a board, and a cubit and a half shall be the width of each board. ¹⁷ Two ^[a]tenons shall be in each board for binding one to another. Thus you shall make for all the boards of the tabernacle.
