'Couple' in the Bible

You shall make fifty clasps of gold, and couple the curtains one to another with the clasps: and the tabernacle shall be a unit.

You shall couple five curtains by themselves, and six curtains by themselves, and shall double over the sixth curtain in the forefront of the tent.

You shall make fifty clasps of brass, and put the clasps into the loops, and couple the tent together, that it may be one.

He made fifty clasps of brass to couple the tent together, that it might be a unit.
