The answer is: While they disputed who was the greatest disciple

Luke 22:29-30 - In this passage, Jesus assures His disciples that they will sit on thrones judging the twelve tribes of Israel. This promise comes amidst their rivalry for status, reflecting both the human tendency toward competition and Jesus’ call to servant leadership. Their future roles illustrate God’s redemptive plan for His people.

In Luke 22:29-30, Jesus shifts the focus from the competitive banter among His disciples to a higher calling—a promise that carries profound implications. Amidst their debate about who ranks highest among them, His word serves not just as a reassurance, but as a nudge towards humility and purpose. They are not being called to throne themselves in self-importance; rather, they are to lead in service, embodying the spirit of those who follow His teachings.

Interesting trivia: The twelve tribes of Israel have their roots in the sons of Jacob, whose story unravels with a rich tapestry of struggle, blessing, and lineage formation within the Hebrew narrative. The invitation to judge these tribes reflects a restoration of order, reminiscent of God's original intent when He established Israel to reflect His justice and mercy.

Moreover, this moment hints at the reconciliation between God and humanity achieved through Christ. Just as the twelve tribes were meant to preserve God's promises, the disciples are entrusted with a similar call, foreshadowing the global message that transcends to all nations. Plus, these promises extend beyond the original audience—bringing hope and tapping into the universal nature of grace.

Ultimately, Jesus' vision points towards a kingdom defined not by power but by service, demonstrating that true greatness is found in loving and uplifting others.
