Acts 12:11; Psalm 139:1-2 [Latin]And Peter coming to himself, said: Now I know in very deed, that the Lord hath sent his angel, and hath delivered me out of the hand of Herod, and from all the expectation of the people of the Jews.

Nunc scio vere, quia misit Dominus angelum suum: et eripuit me de manu Herodis, et de omni exspectatione plebis Judaeorum. Domine probasti me, et cognovisti me: tu cognovisti sessionem meam, et resurrectionem meam. Gloria Patri, et Filio, et Spiritui Sancto. Sicut erat in principio, et nunc, et semper, et in saecula saeculorum. Amen.
