The answer is: Benjamin

1 Samuel 9:1-2 - Saul was from the smallest clan of the smallest tribe

Saul, Israel's first king, being from the tribe of Benjamin, is a fascinating detail that adds depth to his story. Benjamin, often referred to as the smallest tribe, was associated with both strength and struggle. Interestingly, Benjamin is also the tribe that produced awesome figures like the mean slinger, Ehud, and the beloved Joseph's younger brother, Benjamin himself!

In the context of Israel’s tumultuous history at the time of Saul’s rise to power, it’s worth noting that his kingship reflected a pivotal transition from a loose confederation of tribes to a centralized monarchy. His humble beginnings, coming from the least likely tribe, make his leadership journey even more compelling.

Would you believe that the term "Benjaminite" surfaces as a descriptor for warriors known for their skill in battle? They say that “the Benjaminites could sling a stone at a hair and not miss” (1 Chronicles 12:2)! This detail might hint at why Saul, at least initially, was accepted into the mantle of leadership, as he bore the grit and determination of his lineage.

Modern excavations in the land assigned to Benjamin yield fascinating insights. Cities like Gibeah and Ramah highlight urban development—and it'll remind you that these weren't just names on a map; they were centers for midwifing the next chapters of Israelite culture and politics. Saul’s story is one that transcends his tribe's smallness, echoing the idea that greatness often arises from unexpected origins.
