Exodus 39:19 BBE

¹⁷  And they put the two twisted chains on the two rings at the ends of the priest's bag;

¹⁸  And the other two ends of the chains were joined to the two frames and fixed to the front of the ephod over the arm-holes.

¹⁹  And they made two rings of gold and put them on the two lower ends of the bag, on the inner side nearest to the ephod.

²⁰  And two other gold rings were put on the front of the ephod, over the arm-holes, at the join, and over the worked band.

²¹  And the rings on the bag were fixed to the rings of the ephod by a blue cord, keeping it in place over the band, so that the bag might not get loose, as the Lord gave orders to Moses.
