Definition: Amcat1 refers to an abbreviation that is used in the Bible when referring to the Hebrew name of Jesus Christ. It was originally a shortened form of "Ameichiel," which means "Jew" or "Jehovah," hence the Hebrew name, Amcat. This term was later given by Josephus and later on adopted by Jewish scholars. The abbreviation is used in various contexts where it's important to remember that the full name should always be followed by '1.'
