Exodus 39:22-26

And he made the robe of the ephod of woven work, all of blue; and the hole of the robe in the midst thereof, as the hole of a coat of mail, with a binding round about the hole of it, that it should not be rent. And they made upon the skirts of the robe pomegranates of blue, and purple, and scarlet, and twined linen. And they made bells of pure gold, and put the bells between the pomegranates upon the skirts of the robe round about, between the pomegranates; a bell and a pomegranate, a bell and a pomegranate, upon the skirts of the robe round about, to minister in; as Jehovah commanded Moses.
