We had already explained that Joseph's brothers had taken advantage of failed leadership. Now, Joseph uses the same method.
Although Jacob is the leader of Israel, the brothers are in Egypt, where Joseph is the ruler. When seating the brothers according to age, Joseph had recognized Reuben as their leader, but he did not consult with Reuben about what to do. Judah, recognized by his brothers as their leader, was left out of the process.
Christians can wrongly become leaders through bullying, money, church politics, causing division, etc., and this allows them to attack other Christians successfully. But their leadership power wil disappear when they get to Heaven.
