Mark 1:1

The beginning of the Gospel of Jesus Christ - The evangelist speaks with strict propriety: for the beginning of the Gospel is in the account of John the Baptist, contained in the first paragraph; the Gospel itself in the rest of the book. Mt 3:1; Lu 3:1

Luke 3:1

The fifteenth year of Tiberius - Reckoning from the time when Angustus made him his colleague in the empire. Herod being tetrarch of Galilee - The dominions of Herod the Great were, after his death, divided into four parts or tetrarchies. This Herod his son was tetrarch of Galilee, reigning over that fourth part of his dominions. His brother reigned over two other fourth parts, the region of Iturea, and that of Trachonitis (that tract of land on the other side Jordan, which had formerly belonged to the tribe of Manasseh.) And Lysanias (probably descended from a prince of that name, who was some years before governor of that country) was tetrarch of the remaining part of Abilene, which was a large city of Syria, whose territories reached to Lebanon and Damascus, and contained great numbers of Jews. Mt 3:1; Mr 1:1.
