Exodus 39:22-26

Robe. They made the robe for the Ephod entirely of blue. The opening of the robe at the center was like a collar, the edge hemmed so that it wouldn’t tear. On the hem of the robe they made pomegranates of blue, purple, and scarlet material and fine twisted linen. They also made bells of pure gold and alternated the bells and pomegranates—a bell and a pomegranate, a bell and a pomegranate—all around the hem of the robe that was worn for ministering, just as GOD had commanded Moses.
