And you shall make for the breastpiece two rings of gold, and put the two rings on the two edges of the breastpiece.
The most considerable of the ornaments of the high priest was this breast-plate, a rich piece of cloth, curiously wrought with gold and purple, etc., two spans long and a span broad, so that, being doubled, it was a span square, Exo 28:16.
Commenting on Exodus 28:15-30
And thou shalt put two wreathen chains of gold in the two rings,.... This expresses both how many chains were to be made, which is not before said, and the use of them, or where they were to be put, as well as the use of the rings: which are on the ends of the breastplate; the two uppermost ends or corners of it.
And thou shalt make upon the breastplate two rings of gold, and shalt put the two rings on the two ends of the breastplate. (k) Which are upmost toward the shoulder.
