Luke 1:10

And all the... people were praying without: i.e. in that part of the temple called the court of the Israelites. For the Jews themselves were not permitted to enter into the first part of the tabernacle, called the holy, much less into the second part of it, called the holy of holies; the people then prayed, and performed their private devotions, in that division of the temple called the court of the Israelites, and were there waiting for the coming out of the priest Zacharias. (Witham) --- We here see that the priest's functions profited the people, though they neither heard not saw the priest, but only joined in intention with him; and so may the prayers of the priest in the Catholic Church, though offered up in an unknown tongue.
