Exodus 28:33 WEB

³¹  'You shall make the robe of the ephod all of blue.

³²  It shall have a hole for the head in the midst of it: it shall have a binding of woven work round about the hole of it, as it were the hole of a coat of mail, that it not be torn.

³³  On its hem you shall make pomegranates of blue, and of purple, and of scarlet, around its hem; and bells of gold between them round about:

³⁴  a golden bell and a pomegranate, a golden bell and a pomegranate, on the hem of the robe round about.

³⁵  It shall be on Aaron to minister: and the sound of it shall be heard when he goes in to the holy place before Yahweh, and when he comes out, that he not die.
