Exodus 39:22-26

He made the robe of the ephod of woven work, all of blue. And there was an opening in the middle of the robe, like the opening in a coat of mail, with a woven binding all around the opening, so that it would not tear. They made on the hem of the robe pomegranates of blue, purple, and scarlet, and of fine woven linen. And they made bells of pure gold, and put the bells between the pomegranates on the hem of the robe all around between the pomegranates: a bell and a pomegranate, a bell and a pomegranate, all around the hem of the robe to minister in, as the LORD had commanded Moses.
