“As a symbol of this, the High Priest had two stones on his ephod: one on the right side and the other on the left. And on these were written the twelve names of the sons of Israel: six names on one stone and six names on the other—and they were made of lucid and ardent onyx, through which faith in the humanity and divinity is expressed. And they are likewise expressed in the Creed composed by the twelve apostles. And a sacrifice made in such faith as this is pleasing to God.”
