'Arts' in the Bible

But 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.

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

And many of those that practised curious arts brought their books of charms and burnt them before all. And they reckoned up the prices of them, and found it fifty thousand pieces of silver.
