Babylonia had many gods, one of which was Nebo or Nabo. He was a prophet or herald and patron of scholars and the god of astrology. He was later picked up by the Ancient Greeks as Hermes and the Romans Mercury.
Nebo is in the Old Testament, but not as a god worshiped, instead as a site where worshipers gathered in his name. Britannica XI hints that Nebuchadnezzar from the Book of Daniel was named after the god, or is the god. It is hard to tell in pagan religions as the god and man were often intermixed — Asian empires elevated their kings to a godhead and often after becoming the emperor they took a god’s name. Britannica’s reasoning does make sense, at least etymologically, but none of that is substantiated.
