Exodus 36:17 WBT

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

¹⁸  And he made fifty buttons [of] brass to couple the tent together, that it might be one.

¹⁹  And he made a covering for the tent [of] rams' skins dyed red, and a covering [of] badgers' skins above [that].
