21 At that time the Roman emperor, Augustus, decreed that a census should be taken throughout the Roman Empire. 2 (This was the first census taken when Quirinius was governor of Syria.) 3 All returned to their own ancestral towns to register for this census. 4 And because Joseph was a descendant of King David, he had to go to Bethlehem in Judea, David's ancient home. He traveled there from the village of Nazareth in Galilee. 5 He took with him Mary, his fiancée, who was now obviously pregnant.
Matthew Henry's Commentary on Luke 2:1-5
Commentary on Luke 2:1-7
(Read Luke 2:1-7)
The fulness of time was now come, when God would send forth his Son, made of a woman, and made under the law. The circumstances of his birth were very mean. Christ was born at an inn; he came into the world to sojourn here for awhile, as at an inn, and to teach us to do likewise. We are become by sin like an outcast infant, helpless and forlorn; and such a one was Christ. He well knew how unwilling we are to be meanly lodged, clothed, or fed; how we desire to have our children decorated and indulged; how apt the poor are to envy the rich, and how prone the rich to disdain the poor. But when we by faith view the Son of God being made man and lying in a manger, our vanity, ambition, and envy are checked. We cannot, with this object rightly before us, seek great things for ourselves or our children.
