Matthew 17 : 10-13
At that time, the disciples of Jesus asked Him, “Why do the teachers of the Law say that Elijah must come first?” And Jesus answered, “So it is : first comes Elijah to set everything as it has to be. But I tell you, Elijah has already come, but they did not recognise him, and treated him as they pleased. And they will also make the Son of Man suffer.”
Then the disciples understood that Jesus was referring to John the Baptist.

At that time, Mary then set out for a town in the hill country of Judah. She entered the house of Zechariah and greeted Elizabeth. When Elizabeth heard Mary’s greeting, the baby leapt in her womb.
Elizabeth was filled with Holy Spirit, and giving a loud cry, said, “You are most blessed among women, and Blessed is the Fruit of your womb! How is it that the mother of my Lord comes to me? The moment your greeting sounded in my ears, the baby within me suddenly leapt for joy. Blessed are you who believed that the Lord’s word would come true!”
And Mary said, “My soul proclaims the greatness of the Lord, my spirit exults in God my Saviour!”
