Definition: Apology (from Latin, "apologis", "request for forgiveness") is a formal or informal expression of regret for an action that has been done wrong or ill-advised. It can be used to apologize for something you have done unintentionally or to say sorry when you realize what went wrong. In the Bible, it refers specifically to a man who was accused by his wife of cheating on her in a scandalous way and returned to her home without telling her.
