Exodus 26:4-6

YLT(i) 4 `And thou hast made loops of blue upon the edge of the one curtain, at the end in the joining; and so thou makest in the edge of the outermost curtain, in the joining of the second. 5 fifty loops thou dost make in the one curtain, and fifty loops thou dost make in the edge of the curtain which is in the joining of the second, causing the loops to take hold one unto another; 6 and thou hast made fifty hooks of gold, and hast joined the curtains one to another by the hooks, and the tabernacle hath been one.
