'Reviling' in the Bible
Those who were passing by were insulting Him with abusive and insolent language, wagging their heads [as a sign of contempt], and saying, “Ha! You who would destroy the temple and rebuild it in [only] three days,
And they were saying many other [evil and slanderous] things against Him, blaspheming [speaking sacrilegiously and abusively about] Him.
But when the Jews saw the crowds, they were filled with jealousy and began contradicting the things said by Paul, and were slandering him.
But since the Jews kept resisting and opposing him, and blaspheming [God], he shook out his robe and said to them, “Your blood (damnation) be on your own heads! I am innocent of it. From now on I will go to the Gentiles.”
But when some were becoming hardened and disobedient [to the word of God], discrediting and speaking evil of the Way (Jesus, Christianity) before the congregation, Paul left them, taking the disciples with him, and went on holding daily discussions in the lecture hall of Tyrannus [instead of in the synagogue].
But actually, I have written to you not to associate with any so-called [Christian] brother if he is sexually immoral or greedy, or is an idolater [devoted to anything that takes the place of God], or is a reviler [who insults or slanders or otherwise verbally abuses others], or is a drunkard or a swindler—you must not so much as eat with such a person.
