30 You shall put in the breastplate of judgment the Urim and the Tummim; and they shall be on Aharon's heart, when he goes in before the LORD: and Aharon shall bear the judgment of the children of Yisra'el on his heart before the LORD continually.
30
Also put the Urim and the Thummim in the breastpiece, so they may be over Aaron’s heart whenever he enters the presence of the LORD. Thus Aaron will always bear the means of making decisions for the Israelites over his heart before the LORD.
