This is what they did in the book of Acts to defeat the devil 19:19, Many of them also which used curious arts brought their books together, and burned them before all men: and they counted the price of them, and found it fifty thousand pieces of silver.
This was a fortune, Thirty pieces of silver was the price of a slave. It would amount to 1,666 and 2/3 slaves.
They brought untold wealth into the street and burned it. It was brought out publicly and destroyed, so that nothing of the devil's power could remain.
