'Practicing' in the Bible

For the fool speaks nonsense,And his heart (mind) plans wickedness:To practice ungodliness and to speak error concerning the Lord,To keep the craving of the hungry unsatisfiedAnd to deprive the thirsty of drink.

Then the Lord said to me, “The [counterfeit] prophets are prophesying lies in My Name. I have neither sent them nor authorized them nor spoken to them. They are prophesying to you made-up visions [pretending to call forth responses from handmade gods], a worthless divination and the deceit of their own mind.
