Lu 3:1
3:1 Now {1} in the fifteenth year of the reign of Tiberius
    Caesar, Pontius Pilate being governor of Judaea, and Herod
    being tetrarch of Galilee, and his brother Philip tetrarch
    of Ituraea and of the region of Trachonitis, and Lysanias
    the tetrarch of Abilene,

 (1) John comes at the time foretold by the prophets and lays
     the foundation of the gospel which is exhibited unto us,
     setting forth the true observing of the law and free mercy
     in Christ, which comes after John, using also baptism which
     is the outward sign both of regeneration and also
     forgiveness of sins.

Lu 3:2
3:2 {a} Annas and Caiaphas being the high priests, the word of
    God came unto John the son of Zacharias in the wilderness.

    (a) Josephus calls him Ananus.

Lu 3:13
3:13 And he said unto them, Exact no more than that which is {b}
     appointed you.

     (b) Require no more than that sum that is appointed for the
         tribute money.

Lu 3:14
3:14 And the soldiers likewise demanded of him, saying, And what
     shall we do? And he said unto them, Do violence to no man,
     neither accuse [any] falsely; and be content with your {c}
     wages.

     (c) Which was paid to them partly in money and partly in
         food.

Lu 3:15
3:15 {2} And as the people were in expectation, and all men
     mused in their hearts of John, whether he were the Christ,
     or not;

 (2) If we would rightly and fruitfully receive the sacraments,
     we must neither rest in the signs, neither in him that
     ministers the signs, but lift up our eyes to Christ, who is
     the author of the sacraments, and the giver of that which
     is represented by the sacraments.

Lu 3:17
3:17 {3} Whose fan [is] in his hand, and he will throughly purge
     his floor, and will gather the wheat into his garner; but
     the chaff he will burn with fire unquenchable.

 (3) The gospel is the fan of the world.

Lu 3:19
3:19 {4} But Herod the tetrarch, being reproved by him for
     Herodias his brother Philip's wife, and for all the evils
     which Herod had done,

 (4) John's preaching is confirmed with his death.

Lu 3:21
3:21 {5} Now when all the people were baptized, it came to pass,
     that Jesus also being baptized, and praying, the heaven was
     opened,

 (5) Our baptism is sanctified in the head of the Church, and
     Christ also by the voice of the Father is pronounced to be
     our everlasting King, Priest, and Prophet.

Lu 3:23
3:23 {6} And Jesus himself began to be about thirty years of
     age, being (as was supposed) the son of Joseph, which was
     [the son] of Heli,

 (6) Christ's lineage, according to the flesh, is traced back
     even to Adam, and so to God, that it might appear that it
     was only he whom God promised to Abraham and David, and
     appointed from everlasting to his Church, which is composed
     of all sorts of men.
