Exodus 26:4-6

KJ2000(i) 4 And you shall make loops of blue upon the edge of the outmost curtain from the first set; and likewise shall you make in the edge of the outmost curtain, in the coupling of the second set. 5 Fifty loops shall you make in the one curtain, and fifty loops shall you make in the edge of the curtain that is in the second set; that the loops may take hold one of another. 6 And you shall make fifty clasps of gold, and couple the curtains together with the clasps: and it shall be one tabernacle.
