'Worn' in the Bible
"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.
and worn on Aaron's forehead in order to take away any guilt contained in the holy things which the Israelis consecrate as holy gifts. It is to remain on his forehead continuously, so they may be accepted in the LORD's presence.
