Definition: "Confidential" in ancient Hebrew means "hidden." When an individual or group seeks to maintain secrecy, they use this term in the context of a secret message or information. The letter E stands for "End," which in Hebrew means "end" or "termination." In the Old Testament, it appears frequently as part of commands and judgments to control individuals or groups. For instance, in Deuteronomy 14:3, God instructs, "And if a man is found not to be bound to these words and commandments of mine, then he must have done such things." Therefore, 'E54.conf' means to hold the secret within oneself or through secrecy, as though it were sealed and not revealed.
