Exodus 28:30-32

Darby Translation

³⁰ And thou shalt put into the breastplate of judgment the Urim and the Thummim, that they may be upon Aaron's heart when he goeth in before Jehovah; and Aaron shall bear the judgment of the children of Israel upon his heart before Jehovah continually.

³¹ And thou shalt make the cloak of the ephod all of blue.

³² And its opening for the head shall be in the midst thereof; there shall be a binding of woven work at its opening round about; as the opening of a coat of mail, it shall be in it—it shall not rend.
