The answer is: Aaron

Num 26:59 - Miriam was their sister. Aaron was 3 years older than Moses (Exo 7:7).

Moses, that iconic leader and central figure of the Exodus, had a prominent brother named Aaron who played a key role in the story of Israel's liberation from Egypt. Being older by three years, Aaron took on the title of the first high priest, assuming an essential identity in the spiritual and community life of the Israelites.

It's fascinating how sibling dynamics are highlighted throughout the Bible. While Moses often speaks directly with God, seeking guidance and communicationion with the divine, it is Aaron who emerges as the spokesperson for Moses—carrying forth the messages pharaoh needed to hear. The team of Moses and Aaron isn't just a duo; it symbolizes partnership in fulfilling a purpose larger than themselves.

Of course, Aaron's story doesn't stop at the Exodus. He is respected within Jewish tradition and even credited for the establishment of the priesthood, originating the line that eventually led to the Levites. Speaking of his gifts, Aaron’s sympathetic nature and diplomatic skills can be seen as symbolic—a reminder of the vital role of mediation and community leaders in spiritual growth.

By the way, did you know that Miriam, their sister, also played a crucial role in their narratives? She led the women in song after the crossing of the Red Sea. This trio of siblings collaborates in overcoming immense challenges, illustrating how interconnectedness and leadership can drive progress, resilience, and faith!
