'Practised' in the Bible

But he who has heard and not practised is like a man who has built a house upon the soft soil without a foundation, against which the torrent bursts, and immediately it collapses, and terrible is the wreck and ruin of that house."

and not a few of those who had practised magical arts brought their books together and burnt them in the presence of all. The total value was reckoned and found to be 50,000 silver coins.
