3. The voice of one crying in the wilderness: “Prepare the way of the Lord; Make straight [b]in the desert A highway for our God. 4 Every valley shall be exalted And every mountain and hill brought low; The crooked places shall be made [c]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
