Mark 1:2-6

just as it is written in Isaiah the prophet: “Behold, I am sending My messenger before You, Who will prepare Your way;

The voice of one calling out in the wilderness, ‘Prepare the way of the Lord, Make His paths straight!’ ”

John the Baptist appeared in the wilderness, preaching a baptism of repentance for the forgiveness of sins.

And all the country of Judea was going out to him, and all the people of Jerusalem; and they were being baptized by him in the Jordan River, confessing their sins.

John was clothed with camel’s hair and wore a leather belt around his waist, and his diet was locusts and wild honey.
