'Practicing' in the Bible

People deceive their friends, and they don't tell the truth. They have taught their tongues to tell lies. They exhaust themselves practicing evil.

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.

But your eyes and heart are on nothing but your dishonest gain, shedding the blood of innocent people, and practicing oppression and extortion."

So do not listen to your prophets or to those who claim to predict the future by divination, by dreams, by consulting the dead, or by practicing magic. They keep telling you, 'You do not need to be subject to the king of Babylon.'
