Exodus 39:22-26

221Then he made the robe of the ephod of woven work, all of 2blue; 233and the opening of the robe was at the top in the center, as the opening of a coat of mail, with a binding all around its opening, so that it would not be torn. 24They made pomegranates of 4blue and purple and scarlet material and twisted linen on the hem of the robe. 25They also made bells of pure gold, and put the bells between the pomegranates all around on the hem of the 5robe, 266alternating a bell and a pomegranate all around on the hem of the robe for the service, just as the Lord had commanded Moses.
