Collier's New Encyclopedia (1921)/Aaron
AARON, son of Amram (tribe of Levi), elder brother of Moses, and divinely appointed to be his spokesman in the embassy to the court of Pharaoh. By the same authority, avouched in the budding of his rod, he was chosen the first high-priest. He was recreant to his trust in the absence of Moses upon the Mount, and made the golden calf for the people to worship. He died on Mount Hor in the 123d year of his age; and the high-priesthood descended to his third son, Eleazar.
Aaron's rod, in archaeology, is a rod like that of Mercury, but with only one serpent, instead of two, twined around it.
