Acts 8:5-13

5And Philip went down to the city of Samaria, and proclaimed unto them the Christ. 6And the multitudes gave heed with one accord unto the things that were spoken by Philip, when they heard, and saw the signs which he did. 7For from many of those that had unclean spirits, they came out, crying with a loud voice: and many that were palsied, and that were lame, were healed. 8And there was much joy in that city.

9But there was a certain man, Simon by name, who beforetime in the city used sorcery, and amazed the people of Samaria, giving out that himself was some great one: 10to whom they all gave heed, from the least to the greatest, saying, This man is that power of God which is called Great. 11And they gave heed to him, because that of long time he had amazed them with his sorceries. 12But 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. 13And Simon also himself believed: and being baptized, he continued with Philip; and beholding signs and great miracles wrought, he was amazed.
