Exodus 28:22-26

You shall also make on the breastpiece twisted chains of cord work in pure gold.

And you shall make on the breastpiece two rings of gold, and shall put the two rings on the two ends of the breastpiece.

And you shall put the two cords of gold on the two rings at the ends of the breastpiece.

You shall put the other two ends of the two cords on the two filigree settings, and put them on the shoulder pieces of the ephod, at the front of it.

And you shall make two rings of gold and place them on the two ends of the breastpiece, on the edge of it, which is toward the inner side of the ephod.
