Exodus 26:9

And thou shalt join the five skins together, and the six skins together; and thou shalt double the sixth skin in front of the tabernacle.

And thou shalt couple five curtains by themselves, and six curtains by themselves, and shalt double the sixth curtain in the forefront of the tabernacle.

You shall couple five curtains by themselves, and six curtains by themselves, and shall double over the sixth curtain in the forefront of the tent.
