'High Priest' in the Bible

You shall put the two stones on the [two] shoulder pieces of the ephod [of the high priest], as memorial stones for Israel; and Aaron shall bear their names on his two shoulders as a memorial before the Lord.

"You are to make a breast piece to be worn by the high priest when he makes legal decisions. It is to be skillfully worked, made like the work of the ephod from gold, blue, purple, and scarlet material, and from fine woven linen.

"Aaron is to carry the names of Israel's sons on his heart on the breast piece to be worn by the high priest when he makes legal decisions, that is, whenever he goes into the Holy Place in order to remember them continuously in the LORD's presence.

In the breastpiece of judgment you shall put the Urim (Lights) and the Thummim (Perfections) [to be used for determining God’s will in a matter]. They shall be over Aaron’s heart whenever he goes before the Lord, and Aaron shall always carry the judgment (verdict, judicial decisions) of the sons of Israel over his heart before the Lord.

There was a bell and a pomegranate, then a bell and a pomegranate, all around the hem of the robe for when the High Priest ministered, just as the LORD commanded Moses.
