1. Being charged with an unsound or raving mind · dominant

   In Acts 12:15, the second-person singular form is addressed to a woman after her report is rejected; the APB renders the reply, "You are raving." In Acts 26:24 the same form is shouted at Paul during his defense, while John 10:20 reports that many made the charge about Jesus; 1 Corinthians 14:23 anticipates outsiders making such a judgment about an assembly. Acts 26:25 uses the first-person singular in Paul’s denial of that accusation; the APB renders, "I am not out of my mind."

In the Anselm Project Bible: The APB variously presents the charge as "raving," "out of your mind," and "insane," and presents Paul’s reply as a denial. These are verse-level renderings rather than separate lexical meanings.
