Exodus 36:8-13

8And every wise-hearted man among those that wrought the work of the tabernacle made ten curtains of twined byssus, and blue, and purple, and scarlet: [with] cherubim of artistic work did he make them.

9The length of one curtain was twenty-eight cubits, and the breadth of one curtain four cubits — one measure for all the curtains.

10And he coupled five of the curtains one to another, and [the other] five curtains coupled he one to another.

11And he made loops of blue on the edge of one curtain at the edge of the coupling; he did likewise in the edge of the outermost curtain in the other coupling.

12He made fifty loops in one curtain, and he made fifty loops at the end of the curtain that was in the other coupling: the loops were opposite to one another.

13And he made fifty clasps of gold, and coupled the curtains together with the clasps, so that the tabernacle became one.
