Luke 3:3–6 (NKJV): 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.
5Every valley shall be filled
And every mountain and hill brought low;
The crooked places shall be made straight
And the rough ways smooth;
6And all flesh shall see the salvation of God.’ ”
