Exodus 26:9-11

Amplified Bible

⁹ You shall join five curtains by themselves and the other six curtains by themselves, and you shall double over the sixth curtain at the front of the tent [to make a closed door]. ¹⁰ Make fifty loops on the edge of the outermost curtain in the first set, and fifty loops on the edge of the outermost curtain in the second set.

¹¹ “You shall make fifty bronze hooks and put the hooks into the loops and join the tent together so that it may be one unit.
