Giancarlo Biguzzi, «Witnessing Two by Two in the Acts of the Apostles.», Vol. 92 (2011) 1-20
The program of Act 1,8 is carried through by the Twelve only in Jerusalem, Samaria and the Mediterranean coast, — but not «till the end of the earth». Their witness, however, is prolonged by the Seven of Jerusalem, the Five of Syrian Antioch, and the Seven companions of Paul of Act 20,4. Surprisingly, for everyone of the four groups of witnesses, the author narrates then the witnessing of only two of them. The narrative lacuna, apparently intentional since it recurs four times, allows Luke to involve the reader in reconstructing the spread of the gospel in all the directions for the remaining ten twelfths.
