Mark 1:4-8

John the Baptist appeared in the wilderness preaching a baptism of repentance for the forgiveness of sins [that is, requiring a change of one’s old way of thinking, turning away from sin and seeking God and His righteousness]. And all the country of Judea and all the people of Jerusalem were continually going out to him; and they were being baptized by him in the Jordan River, as they confessed their sins. John wore clothing made of camel’s hair and had a [wide] leather band around his waist, and he ate locusts and wild honey. [Lev 11:22; 2 Kin 1:8] And he was preaching, saying, “After me comes He who is mightier [more powerful, more noble] than I, and I am not worthy to stoop down and untie the straps of His sandals [even as His slave]. As for me, I baptized you [who came to me] with water [only]; but He will baptize you [who truly repent] with the Holy Spirit.”
