Exodus 26:15 KJV

And the remnant that remaineth of the curtains of the tent, the half curtain that remaineth, shall hang over the backside of the tabernacle.

And a cubit on the one side, and a cubit on the other side of that which remaineth in the length of the curtains of the tent, it shall hang over the sides of the tabernacle on this side and on that side, to cover it.^*

And thou shalt make a covering for the tent of rams’ skins dyed red, and a covering above of badgers’ skins.

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

Two tenons shall there be in one board, set in order one against another: thus shalt thou make for all the boards of the tabernacle.^*

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