The answer is: Othniel

Jdg 1:13 / Josh 15:13 - Othniel was from the family of Caleb of Judah. Ibzan may possibly have been from Judah but is perhaps more likely to be from Bethlehem in Zebulun, not Judah, we don't know.

Let's delve a little deeper into our friend Othniel, a rather unsung hero of the biblical narrative. You might know him as the first judge, stepping into leadership after Israel's cry for help against their enemies in the land of Canaan. In Judges 3:9-10, we're given insight about Othniel being empowered by the Spirit of the Lord, which is significant - it hints at the divine endorsement of his role. As a sprightly uncle of Caleb, one of the Bible's original spies, looks like Othniel didn’t just emerge out of the blue; he had a strong legacy!

Fun fact: Othniel’s swagger lands him not just on the roster of Judges but makes him an emphasis of Israel's leadership lineage. The role of judges was paramount in a time marked by ‘Do what is right in your own eyes’ (Judges 21:25). Picture it—Israel was like a toddler without a parent! Othniel brought a touch of order back to the chaos.

Additionally, though the house of Judah emerges strong with various judges, Othniel's uniqueness denotes that sometimes, the most significant qualities can be found in characters who show quiet resolve rather than loud military prowess, much like David later on. Echoes of further adventures can be seen in the successes of later Judah figures. How Othniel rode his wave of faithfulness really set the scene for an engaging, ongoing narrative through the book!
