Exodus 26:16-18

21st Century King James Version

¹⁶ Ten cubits shall be the length of a board, and a cubit and a half shall be the breadth of one board.

¹⁷ Two tenons shall there be in one board, set in order to join one to another. Thus shalt thou make for all the boards of the tabernacle.

¹⁸ And thou shalt make the boards for the tabernacle, twenty boards for the south side southward.
