The answer is: Joshua

Ex 17:8

Moses' decision to solicit Joshua in his battle against the Amalekites is indeed a significant moment in biblical history. It emphasizes not just the leadership of Moses but also the potential and promise within Joshua. This selection marks the beginning of Joshua’s path to prominence and ultimately his role as Moses' successor and the leader who would guide the Israelites into the Promised Land.

Fun fact: Joshua's name actually means "Yahweh is salvation," and he plays a crucial role not just as a warrior but also as a devoted servant and disciple under Moses. Before their battle against the Amalekites, there’s no evidence of his military experience, highlighting that God often selects unlikely heroes for significant leadership roles, focusing on their character rather than their prior accomplishments.

The conflict with Amalek, however, draws attention to deeper themes in the text. Amalek symbolizes those who oppose the Israelites, and God’s command in Deuteronomy (25:17-19) declares that their memory should be blotted out for such opposition. This motif of struggle against enemies of the people reflects continuity, reminding us that challenges are an enduring aspect of the spiritual journey.

In Exodus 17:12, it’s interesting to note that whenever Moses raised his hands, Israel prevailed; when he lowered them, Amalek prevailed. This visualizes a powerful lesson on the importance of reliance on divine help. Moses needed help—so he recruited Aaron and Hur, illustrating the community aspect of leadership and the strength found in collaboration and support. Certainly, echoing themes of unity and perseverance can be found throughout the Bible, resonating in many other classic stories where allies are needed to achieve victory against adversity.
