Aaron was Moses’ brother and his spokesperson before Israel and Pharaoh. When Pharaoh refused to release the Hebrews, Aaron stretched out his rod to bring plagues upon the Egyptians. He helped Moses lead the Israelites out of Egypt and through the wilderness. At Sinai, however, Aaron gave in to the Israelites’ sinful demand and designed a golden calf for them to worship. On another occasion, when the Lord miraculously provided water in the wilderness, both Moses and Aaron failed to give proper honor to the Lord, and as a result they were forbidden entry into the Promised Land. As a descendant of Levi, Aaron became Israel’s first high priest, and all future priests were his descendants. (Exodus 4:15)
