Exodus 26:4-6

Amplified Bible, Classic Edition

⁴ And you shall make loops of blue on the edge of the last curtain in the first set, and likewise in the second set.

⁵ Fifty loops you shall make on the one curtain and fifty loops on the edge of the last curtain that is in the second coupling or set, so that the loops on one correspond to the loops on the other.

⁶ And you shall make fifty clasps of gold and fasten the curtains together with the clasps; then the tabernacle shall be one whole.
