Exodus 28:31-34

31And thou shalt make the robe of the ephod all of blue. 32And there shall be an hole in the top of it, in the midst thereof: it shall have a binding of woven work round about the hole of it, as it were the hole of a garment, that it be not rent.

33And beneath upon the hem of it thou shalt make pomegranates of blue, and of purple, and of scarlet, round about the hem thereof; and bells of gold between them round about:1 34A golden bell and a pomegranate, a golden bell and a pomegranate, upon the hem of the robe round about.
