The blue robe (Ex 39:22-39:26)

“He also made the robe of the ephod woven all of blue yarn.  The opening of the robe in the middle of it was like the opening in a coat of mail, with a binding around the opening, so that it might not be torn.  On the lower hem of the robe, they made pomegranates of blue, purple, and crimson yarns, and of fine twisted linen. They also made bells of pure gold.  They put the bells between the pomegranates on the lower hem of the robe all around, between the pomegranates.  There was a bell and a pomegranate, a bell and a pomegranate all around on the lower hem of the robe for ministering, just as Yahweh had commanded Moses.”

Once again they are doing what Yahweh had commanded Moses in chapter 28.  This robe is only blue but with a opening in the middle.    The lower hem of the robe alternated between a gold bell and a colorful pomegranate all around the hem.  You obviously could tell when someone wearing this robe was coming.
