¹⁶ Each board shall be ten cubits long and one and a half cubits wide. ¹⁷ Each board shall have two joints in it to fit them together. All the boards of the tabernacle are to be made this way. ¹⁸ This is how you shall make all the boards for the tabernacle, twenty boards being on the southern side.
