The answer is: Aaron

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

Ah, the famous trio of siblings that led the Israelites out of Egypt! Moses, Aaron, and Miriam are key figures within the Exodus narrative, each playing an essential role. Aaron served not just as Moses’ elder brother but also as the first high priest, highlighting the significance of familial ties and their leadership in shaping Israel’s identity.

Did you know Aaron’s name means “mountain of strength”? Makes sense, considering he was a formidable figure during the hard times in the desert! His close relationship with Moses was evident when God appointed him as Moses' spokesperson due to Moses’ initial hesitation. Imagine having to lead an entire nation and magic away the uncertainties with your brother holding your hand.

Miriam, on the other hand, is often celebrated as a prophetess and a woman of great courage, watching over baby Moses when he was set afloat in a basket and assuring Pharaoh’s daughter of his heritage—which is another fascinating twist in this tale. One could see a lively familial dynamic mirroring many family cultures today; think about how sibling roles coordinate during challenging times.

In the grander context of the Exodus, this sibling trio represents unity against adversity. While they faced immense struggles, together their faith—and additional figures of leadership such as elders or unknowingly, even foes—propelled them forward to freedom. It's a timeless reminder of how interconnected we all are in our spiritual journeys and historic narratives.
