On high state occasions he wore the costly garments and the “shining plate” of gold on his linen turban. He also wore the breastpiece that contained the Urim and Thummim, enabling him to receive Jehovah’s “Yes” or “No” to national problems;

Moses dressed Aaron in beautiful garments of gold, blue, purple, and scarlet materials, including shoulder pieces and a breastpiece that was adorned with precious gems of varied colors. On his head was placed a turban of fine linen. Attached to it was a plate of pure gold, engraved with the words “Holiness belongs to Jehovah.” (Le 8:7-9; Ex 28)
