Luke 3:3-6 NIV

[3] He went into all the country around the Jordan, preaching a baptism of repentance for the forgiveness of sins. [4] As it is written in the book of the words of Isaiah the prophet: “A voice of one calling in the wilderness, ‘Prepare the way for the Lord, make straight paths for him. [5] Every valley shall be filled in, every mountain and hill made low. The crooked roads shall become straight, the rough ways smooth. [6] And all people will see God’s salvation.’ ”
