The answer is: Joshua

Ex 17:8

Moses, a pivotal figure in the Exodus story, had an intriguing right-hand man named Joshua. When pop-up агression from the Amalekites threatened the Israelites, Moses didn't leap into battle himself. Instead, he appointed Joshua to lead the troops against these foes—a practical move that shows a keen sense of delegation. This moment is not just a tactical decision; it's a glimpse into Moses' growing trust in his young assistant, who would later become the leader of the Israelites.

Interestingly, this episode in Exodus marks the first accounts of the military capabilities of the Israelite community as they establish themselves after escaping slavery in Egypt. It stands out because, in the face of adversity, the Israelites are starting to find their identity through strength and unity. Plus, Joshua's name means "Yahweh is salvation," which is significant considering his role in future attempts to get the Israelites to the Promised Land.

The Amalekites were notorious for their guerilla-style attacks. Their encounter with the Israelites hints at the challenges of survival in those ancient and rugged times; they weren't just battling other peoples, but also climatic and logistical struggles. And as a little trivia nugget, the Amalekites have become a symbolic enemy in Jewish history, representing ultimate aggression against the chosen people. Each drama-filled memory serves to remind future generations of resilience and the quest for belonging towards a promised hope.
