'Reviler' in the Bible

'Bring out the reviler unto the outside of the camp; and all those hearing have laid their hands on his head, and all the company have stoned him.

And Moses speaketh unto the sons of Israel, and they bring out the reviler unto the outside of the camp, and stone him with stones; and the sons of Israel have done as Jehovah hath commanded Moses.

because of the voice of the scorner and reviler,because of the enemy and avenger.

But now I am writing you not to associate with anyone who claims to be a believer who is sexually immoral or greedy, an idolater or verbally abusive, a drunkard or a swindler. Do not even eat with such a person.
