Gospel of Luke, chapter 1, verses 57 to 80:
The time came for Elizabeth to have her child, and she gave birth to a son; and when her neighbours and relations heard that the Lord had lavished on her his faithful love, they shared her joy.
Now it happened that on the eighth day they came to circumcise the child; they were going to call him Zechariah after his father, but his mother spoke up. “No,” she said, “he is to be called John.”
They said to her, “But no one in your family has that name,” and made signs to his father to find out what he wanted him called.
The father asked for a writing-tablet and wrote, “His name is John.” And they were all astonished. At that instant his power of speech returned and he spoke and praised God. All their neighbours were filled with awe and the whole affair was talked about throughout the hill country of Judaea. All those who heard of it treasured it in their hearts. “What will this child turn out to be?” they wondered. And indeed the hand of the Lord was with him.
His father Zechariah was filled with the Holy Spirit and spoke this prophecy:
Blessed be the Lord, the God of Israel, for he has visited his people, he has set them free,
and he has established for us a saving power in the House of his servant David,
just as he proclaimed, by the mouth of his holy prophets from ancient times,
that he would save us from our enemies and from the hands of all those who hate us,
and show faithful love to our ancestors, and so keep in mind his holy covenant.
This was the oath he swore to our father Abraham,
that he would grant us, free from fear, to be delivered from the hands of our enemies,
to serve him in holiness and uprightness in his presence, all our days.
And you, little child, you shall be called Prophet of the Most High, for you will go before the Lord to prepare a way for him,
to give his people knowledge of salvation through the forgiveness of their sins,
because of the faithful love of our God in which the rising Sun has come from on high to visit us,
to give light to those who live in darkness and the shadow dark as death, and to guide our feet into the way of peace.
Meanwhile the child grew up and his spirit grew strong. And he lived in the desert until the day he appeared openly to Israel.
