Shemot 26:4-6

Orthodox Jewish Bible

⁴ And thou shalt make loops of turquoise wool upon the edge of the outermost curtain of the set; and likewise shalt thou make loops upon the edge of the outermost curtain, in the second set.

⁵ Fifty loops shalt thou make in the first curtain, and fifty loops shalt thou make on the edge of the outermost curtain that is in the second set; that the loops may be opposite one another.

⁶ And thou shalt make fifty hooks of zahav, and join the curtains together with the hooks: so that the Mishkan shall become one.
