Acts 8:9-11

9But a certain man, by name Simon, had been before in the city, using magic arts, and astonishing the nation of Samaria, saying that himself was some great one.

10To whom they had all given heed, from small to great, saying, This is the power of 1God which is called great.

11And they gave heed to him, because that for a long time he had astonished them by his magic arts.
