Luke 1:67, 76-79

And his father Zechariah was filled with the Holy Spirit. And he prophesied, saying

And you, child, shall be called the prophet of the Most High. For you will go before the face of the Lord: to prepare his ways, to give knowledge of salvation to his people for the remission of their sins, through the heart of the mercy of our God, by which, descending from on high, he has visited us, to illuminate those who sit in darkness and in the shadow of death, and to direct our feet in the way of peace."
