Mark 1:2-8
2 As it is written in Isaiah the prophet,
“Behold, I send my messenger before your face,
who will prepare your way,
3 the voice of one crying in the wilderness:
‘Prepare the way of the Lord,
make his paths straight,’”
4 John appeared, baptizing in the wilderness and proclaiming a baptism of repentance for the forgiveness of sins. 5 And all the country of Judea and all Jerusalem were going out to him and were being baptized by him in the river Jordan, confessing their sins. 6 Now John was clothed with camel's hair and wore a leather belt around his waist and ate locusts and wild honey. 7 And he preached, saying, “After me comes he who is mightier than I, the strap of whose sandals I am not worthy to stoop down and untie. 8 I have baptized you with water, but he will baptize you with the Holy Spirit.” (ESV)
