Aaron, the first high priest of the Israelites. He was the elder brother of Moses, his spokesman at the court of Pharaoh and his assistant in leading the Jewish nation out from Egypt. During the absence of Moses on Mount Sinai he yielded to the cry of the people and made a golden calf for them to worship. Mount Hor, whereon he died, at the age of 123 years, is still called the "Mount of Aaron."
