Luke 3:2-6

while Annas and Caiaphas were high priests, the word of God came to John the son of Zacharias in the wilderness. And he went into all the region around the Jordan, preaching a baptism of repentance for the remission of sins, as it is written in the book of the words of Isaiah the prophet, saying: “The voice of one crying in the wilderness: ‘Prepare the way of the LORD; Make His paths straight. Every valley shall be filled And every mountain and hill brought low; The crooked places shall be made straight And the rough ways smooth; And all flesh shall see the salvation of God.’ ”
