Atos 13:33
Paul when he was discoursing in the synagogue of Antioch in Pisidia spoke thus: And we bring you good tidings of the promise made unto the fathers, how that God hath fulfilled the same unto us their children in that he raised up Jesus, as it is also written in the second psalm, Thou art my son, this day have I begotten thee. Paul here, by Christ's having been begotten, understands his resurrection, and he too has decided that the second psalm has been spoken concerning him, as all the Apostles also have affirmed. — The Christian Topography, Book 5
