Exodus 28:30-32

New Century Version

³⁰ And put the Urim and Thummim inside the chest covering so that they will be on Aaron’s heart when he goes before the Lord. They will help in making decisions for the Israelites. So Aaron will always carry them with him when he is before the Lord.

³¹ “Make the outer robe to be worn under the holy vest, using only blue cloth. ³² Make a hole in the center for Aaron’s head, with a woven collar around the hole so it will not tear.
