In context
14He then made curtains of goat hair for the tent over the tabernacle — eleven curtains in all. 15Each of the eleven curtains was the same size — thirty cubits long and four cubits wide. 16He joined five of the curtains into one set and the other six into another. 17He made fifty loops along the edge of the end curtain in the first set, and fifty loops along the edge of the corresponding curtain in the second set. 18He also made fifty bronze clasps to join the tent together as a unit. 19Additionally, he made for the tent a covering of ram skins dyed red, and over that a covering of fine leather.
