Exodus 39:19-21

Living Bible

¹⁹ Two gold rings were also set at the lower edge of the chestpiece, on the under side, next to the ephod. ²⁰ Two other gold rings were placed low on the shoulder straps of the ephod, close to where the ephod joined its beautifully woven sash. ²¹ The chestpiece was held securely above the beautifully woven sash of the ephod by tying the rings of the chestpiece to the rings of the ephod with a blue ribbon.

All this was commanded to Moses by the Lord.
