Exodus 26:4-6

MSB^{(i) 4} Make loops of blue material on the edge of the end curtain in the first set, and do the same for the end curtain in the second set. ⁵ Make fifty loops on one curtain and fifty loops on the end curtain of the second set, so that the loops line up opposite one another. ⁶ Make fifty gold clasps as well, and join the curtains together with the clasps, so that the tabernacle will be a unit.
