⁹ And a certain man, by name Simon, was before in the city using magic, and amazing the nation of Samaria, saying himself to be a certain great one,

¹⁰ to whom they were all giving heed, from small unto great, saying, `This one is the great power of God;'

¹¹ and they were giving heed to him, because of his having for a long time amazed them with deeds of magic.
