On the fourth day of Christmas my True Love gave to me...

The beginning of the gospel of Jesus Christ, the Son of God.
As it is written in Isaiah the prophet,

"Behold, I send my messenger before your face,
who will prepare your way,
the voice of one crying in the wilderness:
'Prepare the way of the Lord,
make His paths straight,'"

John appeared, baptising in the wilderness and proclaiming a baptism of repentance for the forgiveness of sins. And all the country of Judea and all Jerusalem were going out to him and were being baptised by him in the river Jordan, confessing their sins. Now John was clothed with camel's hair and wore a leather belt around his waist and ate locusts and wild honey. And he preached, saying, "After me comes he who is mightier than I, the strap of whose sandals I am not worthy to stoop down and untie. I have baptised you with water, but he will baptise you with the Holy Spirit."
Mark 1:1-8

And Mary said,
"My soul magnifies the Lord,
and my spirit rejoices in God my Savior,
for He has looked on the humble estate of His servant.
For behold, from now on all generations will call me blessed;
for He who is mighty has done great things for me,
and holy is His name.
And His mercy is for those who fear Him
from generation to generation.
He has shown strength with His arm;
He has scattered the proud in the thoughts of their hearts;
He has brought down the mighty from their thrones
and exalted those of humble estate;
He has filled the hungry with good things,
and the rich He has sent empty away.
He has helped His servant Israel,
in remembrance of His mercy,
as He spoke to our fathers,
to Abraham and to his offspring forever."
Luke 1:46-55

Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit. And her husband Joseph, being a just man and unwilling to put her to shame, resolved to divorce her quietly. But as he considered these things, behold, an angel of the Lord appeared to him in a dream, saying, "Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit. She will bear a son, and you shall call his name Jesus, for he will save his people from their sins."
All this took place to fulfill what the Lord had spoken by the prophet:

"Behold, the virgin shall conceive and bear a son,and they shall call his name Immanuel"

(which means, God with us). When Joseph woke from sleep, he did as the angel of the Lord commanded him: he took his wife, but knew her not until she had given birth to a son. And he called his name Jesus.
Matthew 1:18-25

In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through Him, and without Him was not any thing made that was made. In Him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it.

And the Word became flesh and dwelt among us, and we have seen His glory, glory as of the only Son from the Father, full of grace and truth.
John 1:1-5, 14
