The Acts 8:12-17

But when they believed Philip preaching good tidings concerning the kingdom of God and the name of Jesus Christ, they were baptized, both men and women. And Simon also himself believed: and being baptized, he continued with Philip; and beholding signs and great miracles wrought, he was amazed. Now when the apostles which were at Jerusalem heard that Samaria had received the word of God, they sent unto them Peter and John: who, when they were come down, prayed for them, that they might receive the Holy Ghost: for as yet he was fallen upon none of them: only they had been baptized into the name of the Lord Jesus. Then laid they their hands on them, and they received the Holy Ghost.
