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.

Isn't it fascinating that Othniel, judge and hero, comes from the tribe of Judah? This tribe holds a particularly significant place in the Bible's panoramic tale; it’s the lineage of David and, according to Christian tradition, Jesus too! Othniel, who first appears in the spotlight in Joshua and Judges, is the younger brother of Caleb—an inspiring figure himself. Caleb’s prowess and bravery in scouting out the Promised Land show the strength of this family line, affirming their faith and courage.

Here’s a fun trivia nugget: When Othniel became the first judge of Israel following Joshua's leadership, he led the Israelites in battles against foreign oppressors, re-establishing peace and faith among the tribes. He became a symbol of God's assistance during troubling times, reminding us that righteousness often has its rewards.

The label of “judge” brings to mind a community leader skilled in upholding justice rather than cycling through personal grievances or favoritism. What a contrast, when you think about contemporary judicial figures, right?

Also, although Othniel was the only confirmed judge from Judah in this time period, this nod to his bloodline shows how the tribal system operated as a significant theme throughout Israel's history—woven tightly as the heart of an ever-changing plot. Trust in one’s lineage has profound implications, and who knows what untold stories lie in the shadows of less prominent tribes? Keep exploring!
