It's a pretty interesting story when Moses finds himself unable to bear the burdens of the Israelites and God, in return, appoints elders to help lighten the load. As a young leader, Joshua finds himself in a spot of jealousy of the manifestation of the Spirit in other people, and Moses reminds him that there should be no place for jealousy.
Don't we all, like Joshua, desire to be special? It's a legitimate temptation to become jealous of those who have outward gifts that bring them some level of notoriety. The lesson here is that Joshua should have been rejoicing rather than stewing. Any gifts given to us by the Spirit are for the benefit of us all. We should never lord gifts over others nor should we find ourselves being jealous of the gifts of others. Rather, we must all be grateful for what God has graciously given to each one of us.
