Aaron served with Moses as mediators between God and the Egyptian pharaoh. As God’s prophets, Aaron and Moses foretold of 10 plagues God would unleash on Egypt, which threatened the pharaoh into releasing the Israelites. The brothers’ first, risky assignment was to petition for Israel’s release from bondage and permission to leave Egypt. Moses accepted the leadership position with the Lord’s concession that Aaron be Moses' mouthpiece. Aaron was three years older than Moses ( Exodus 7:7), yet Moses was chosen to lead the Hebrews out of Egypt. The most famous Levites born during Israel’s enslavement in Egypt were Aaron and his younger siblings, Moses and Miriam.
