Exodus 39:22-26

22And he made the cloak of the ephod of woven work, all of blue;

23and the opening of the cloak in its middle, as the opening of a coat of mail; a binding was round about the opening, that it should not rend.

24And they made on the skirts of the cloak pomegranates of blue and purple and scarlet, twined.

25And they made bells of pure gold, and put the bells between the pomegranates, in the skirts of the cloak, round about, between the pomegranates:

26a bell and a pomegranate, a bell and a pomegranate, in the skirts of the cloak round about, for service; as Jehovah had commanded Moses.
