TSK · Exodus 7:12

When the magicians attempted to bring forth gnats by their secret arts, they could not. So there were gnats on people and on animals.

Now in that city was a man named Simon, who had been practicing magic and amazing the people of Samaria, claiming to be someone great.

Large numbers of those who had practiced magic collected their books and burned them up in the presence of everyone. When the value of the books was added up, it was found to total fifty thousand silver coins.
