The voice of one crying in the wilderness: "Prepare the way of the LORD; Make straight in the desert A highway for our God. Every valley shall be exalted And every mountain and hill brought low; The crooked places shall be made straight And the rough places smooth; [5] The glory of the LORD shall be revealed, And all flesh shall see it together; For the mouth of the LORD has spoken."
Isaiah 40:3-5 NKJV
while Annas and Caiaphas were high priests, the word of God came to John the son of Zacharias in the wilderness. [3] And he went into all the region around the Jordan, preaching a baptism of repentance for the remission of sins, [4] 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. [5] Every valley shall be filled And every mountain and hill brought low; The crooked places shall be made straight And the rough ways smooth; [6] And all flesh shall see the salvation of God.'"
Luke 3:2-6 NKJV
