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.

Othniel is a fascinating figure, notably mentioned in the Book of Judges as the first judge of Israel. Coming from the tribe of Judah, he was not just any leader, but the nephew of Caleb—one of the original scouts sent into Canaan with Joshua. This lineage is significant because it ties Othniel's judicial authority to the legacy of courage and faith embodied by Caleb.

Fun fact: some believe that Othniel's victory over the city of Debir (Joshua 15:15) was more than just a military triumph; it symbolized faith sparking action. His willingness to tame a challenging situation mirrors themes found throughout the Judges' narrative where God’s spirit commands differing leaders from various tribes, each displaying varying levels of faith and reliance on divine support.

Interestingly, even though the Judges took leadership in cycles of conflict and deliverance, it’s often the relationships between them, like that of Othniel and Caleb, that frame the narrative. By using these familial connections, the text creates a rich tapestry of history and familial allegiance.

Additionally, echoing Uthniel within the broader biblical scope leads us to see that God's chosen not only existed in the direct line of roles such as kings and priests, but extended into everyday tribes and towns, demonstrating divine working through ordinary, albeit gifted, individuals. This shows that wherever we come from or wherever we go, we too can play a role in something much greater if we embrace our calling.
