Section 887
I. The names of the twelve tribes of Israel being engraven on them, they were borne on Aaron's heart
When he went into the holy place on the day of atonement, for a memorial before the Lord, so that what Aaron then did, more especially, he did, not in his own name, but in the name of the whole congregation of Israel; he acted as their representative, when he slew the sacrifice, and carried the blood within the veil, for it was not only for himself, but for all the people.
