BRG Bible

¹⁵ The length of one curtain was thirty cubits, and four cubits was the breadth of one curtain: the eleven curtains were of one size.

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

¹⁷ And he made fifty loops upon the uttermost edge of the curtain in the coupling, and fifty loops made he upon the edge of the curtain which coupleth the second.
