And Joseph also went up from Galilee, from the city of Nazareth, to Judea, to the city of David, which is called Bethlehem, because he was of the house and lineage of David, to be enrolled with Mary, his betrothed, who was with child.

Luke 2:1-20

In those days a decree went out from Caesar Augustus that all the
world should be enrolled. This was the first enrollment, when Quirinius
was governor of Syria. And all went to be enrolled, each to his own
city. And Joseph also went up from Galilee, from the city of Nazareth,
to Judea, to the city of David, which is called Bethlehem, because
he was of the house and lineage of David, to be enrolled with Mary,
his betrothed, who was with child. And while they were there, the
time came for her to be delivered. And she gave birth to her first
born son and wrapped him in swaddling clothes, and laid him in a
manger, because there was no place for them in the inn.

And in that region there were shepherds out in the field, keeping
watch over their flock by night. And an angel of the Lord appeared to
them, and the glory of the Lord shone around them, and they were filled
with fear. And the angel said to them, "Be not afraid; for behold, I
bring you good news of a great joy which will come to all the people;
for to you is born this day in the city of David a Savior, who is
Christ the Lord. And this will be a sign for you: you will find a babe
wrapped in swaddling clothes and lying in a manger." And suddenly there
was with the angel a multitude of the heavenly host praising God and
saying, "Glory to God in the highest, and on earth peace among men with
whom he is pleased!"

When the angels went away from them into heaven, the shepherds said to
one another, "Let us go over to Bethlehem and see this thing that has
happened, which the Lord has made known to us." And they went with haste,
and found Mary and Joseph, and the babe lying in a manger. And when
they saw it they made known the saying which had been told them
concerning this child; and all who heard it wondered at what the shepherds
told them. But Mary kept all these things, pondering them in her
heart. And the shepherds returned, glorifying and praising God for all
they had heard and seen, as it had been told them.
