Mark 1:4-11 New International Version (NIV)
4 And so John the Baptist appeared in the wilderness, preaching a baptism of repentance for the forgiveness of sins. 5 The whole Judean countryside and all the people of Jerusalem went out to him. Confessing their sins, they were baptized by him in the Jordan River. 6 John wore clothing made of camel’s hair, with a leather belt around his waist, and he ate locusts and wild honey. 7 And this was his message: “After me comes the one more powerful than I, the straps of whose sandals I am not worthy to stoop down and untie. 8 I baptize you with water, but he will baptize you with[b] the Holy Spirit.”
The Baptism and Testing of Jesus
9 At that time Jesus came from Nazareth in Galilee and was baptized by John in the Jordan. 10 Just as Jesus was coming up out of the water, he saw heaven being torn open and the Spirit descending on him like a dove. 11 And a voice came from heaven: “You are my Son, whom I love; with you I am well pleased.”
Acts 19:1-7 New International Version (NIV)
Paul in Ephesus
19 While Apollos was at Corinth, Paul took the road through the interior and arrived at Ephesus. There he found some disciples 2 and asked them, “Did you receive the Holy Spirit when you believed?”
They answered, “No, we have not even heard that there is a Holy Spirit.”
3 So Paul asked, “Then what baptism did you receive?”
“John’s baptism,” they replied.
4 Paul said, “John’s baptism was a baptism of repentance. He told the people to believe in the one coming after him, that is, in Jesus.” 5 On hearing this, they were baptized in the name of the Lord Jesus. 6 When Paul placed his hands on them, the Holy Spirit came on them, and they spoke in tongues and prophesied. 7 There were about twelve men in all.
