Mark 1:2-5

As it is written in the prophets, Behold, I send my messenger before thy face, Which shall prepare thy way before thee. The voice of one crying in the wilderness, Prepare ye the way of the Lord, Make his paths straight. John did baptize in the wilderness, and preach the baptism of repentance for the remission of sins. And there went out unto him all the land of Judæa, and they of Jerusalem, and were all baptized of him in the river of Jordan, confessing their sins.
