The answer is: Aaron

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

Moses’ brother Aaron played a vital role as a spokesperson and helper during the Israelites' journey from Egypt to the Promised Land. Interestingly, Aaron is best known for later becoming the first high priest of Israel, establishing a pivotal religious structure within the community.

One of the intriguing aspects of Aaron’s character is how he managed both his nobility and weaknesses. For instance, when Moses went up Mount Sinai to receive the Ten Commandments, it was Aaron who succumbed to the people’s panic and fashioned the golden calf (Exodus 32). This strange incident illustrates the societal pressures leaders may face, as well as the flawed nature of all biblical figures—not just the heroes.

Another fun tidbit is that despite-oriented leadership, Aaron's role emphasized inclusivity in ancient Hebrew society through rituals, festivals, and sacrifices that bind people to their faith.

Moses, Aaron, and their sister Miriam align with the aftermath events focusing on significant familial connections, showcasing the communal aspect of salvation in ancient narratives. Interestingly, the name "Aaron" itself translates to "mountain of strength," which surrounds the spiritual and literal conveyance of Israel’s strength on their journey.

Forever, their story echoes the theme of liberty articulated in spiritual acts striving not just for physical freedom but expected inner transformation! It’s fascinating how these stories stick with us, echoing lessons of leadership, responsibility, and resilience through the ages.
