Exodus 39:20-22

New Life Version

²⁰ Then they made two gold rings and put them on the bottom of the two shoulder pieces of the linen vest in front, near where they join. They were above the belt of the linen vest. ²¹ They tied the rings of the breast-piece to the rings of the linen vest with a blue rope. So the breast-piece could not come loose from the linen vest, just as the Lord had told Moses.

Making Other Pieces of Clothes
