The longest name in the Bible is "Mahershalalhashbaz" which appears in the book of Isaiah (Isaiah 8:1-4). It is a Hebrew name that means "hasten to the spoils" or "swift is the booty". It was given to a son of the prophet Isaiah as a symbolic name to represent the coming invasion and defeat of the Assyrian army who were going to plunder everything in their path.
