Moses' brother and spokesman, and Israel's first high priest.

Aaron was the brother of Moses and Miriam. God met Moses at the burning bush and told him to demand that Pharaoh release the people of Israel from slavery in Egypt. Moses hesitated, claiming that he could not speak well.  Therefore, God said that Aaron would serve as Moses’ spokesman.  When the law was given at Mount Sinai, God designated Aaron as Israel’s first high priest.  Aaron built a golden calf for Israel to worship, which enraged God and Moses, but Aaron was, in time, consecrated as high priest.  Some challenged Aaron, but God confirmed Aaron’s position by miraculously making Aaron’s wooden staff produce buds.  Aaron died in the wilderness and did not enter the promised land.
