Exodus 28:31

The Robe

³⁰ You shall put in the breastpiece of judgment the Urim and the Thummim, and they shall be over Aaron’s heart when he goes in before the Lord; and Aaron shall carry the judgment of the sons of Israel over his heart before the Lord continually. ³¹ “You shall make the robe of the ephod all of blue. ³² There shall be an opening at its top in the middle of it; around its opening there shall be a binding of woven work, like the opening of a coat of mail, so that it will not be torn.
