Exodus 39:22-26

22He also made the robe of the ephod from woven work, all of blue,

23with a hole in the center of the robe, and a binding woven around the hole as a collar, so that it would not be torn.

24They also made, on the hem of the robe, pomegranates of blue, purple, scarlet and twisted linen.

25Then they made bells of pure gold and put the bells between the pomegranates on the hem of the robe all around, between the pomegranates,

26a bell and a pomegranate, then another bell and a pomegranate, all around on the hem of the robe, to minister in, as Adonai commanded Moses.
