Exodus 39:16

And they made the anointing oil, and the incense of composition, and the pure candlestick,

And they made two ouches of gold, and two gold rings; and put the two rings in the two ends of the breastplate.

They made two settings of gold, and two gold rings, and put the two rings on the two ends of the breastplate.

They made also two bosses of golde, and two golde rings, and put the two rings in the two corners of the brest plate.
