Exodus 36:15-17

Darby Translation

¹⁵ The length of one curtain was thirty cubits, and four cubits the breadth of one curtain—one measure for the eleven curtains.

¹⁶ And he coupled five of the curtains by themselves, and six of the curtains by themselves.

¹⁷ And he made fifty loops on the edge of the outermost curtain in the coupling, and fifty loops made he on the edge of the curtain in the other coupling.
