"And thou shalt make two rings of gold, and thou shalt put them upon the two ends of the breastplate, upon the edge thereof, which is toward the side of the ephod inward." — Exodus 28:26 (ASV)

And you shall make two rings of gold
] Two other rings besides those before mentioned:

and you shall put them upon the two ends of the breastplate ;
on the other two ends or corners of it:

in the border thereof which is in the side of the ephod inward :
these were at the two lower ends of the breastplate, towards the ephod on the inside.
