Son of Amram and Jochebed, of the tribe of Levi (Ex. 6: 16-20); elder brother of Moses (Ex. 7: 7). He was appointed by the Lord to assist Moses in bringing the children of Israel out of Egypt and to be his spokesman (Ex. 4: 10-16, 27-31; Ex. 5: 1-Ex. 12: 50). He was with Moses until the fortieth year of the wanderings. At Sinai he was one of those who accompanied Moses up the mountain and saw the Lord (Ex. 19: 24; Ex. 24: 1, 9-11). When Moses and Joshua were called up into the mount to commune with God, Aaron and Hur were appointed judges during their absence (Ex. 24: 14, 18); it was then that Aaron made the golden calf at the people's request (Ex. 32: 1-6, 21, 24, 35). On Mount Sinai Moses received directions about the appointment of Aaron and his four sons, Nadab, Abihu, Eleazar, and Ithamar, to a priesthood that is known as the Aaronic Priesthood (Ex. 28: 1-4; Ex. 29; D&C 84: 18, 26-27). On the completion of the tabernacle Moses consecrated them to their office (Lev. 8: 9-13). Aaron died on Mount Hor at the age of 123 (Num. 20: 22-29; Num. 33: 38-39). For additional items see Ex. 16: 2-10, 33-34; Ex. 18: 12.
