In this weeks parsha, we see a detailed description of the formation of the Jewish Nation in their tribal groups for the travelling through the desert.
I think we can learn a lesson from the detail. Bnei Yisrael could have travelled in a large mass of people, with everyone walking with their friends and family and whoever they wanted. Nothing really would have been wrong with that. So why didn't they travel like that? Why were the instructions of where everyone should be so specific?
I think we can learn a lesson from thsi that everyone has his place in the community. Everybody has what he is supposed to do and where he is supposed to be. Haphazard is no good. We need order and direction in order to function properly and efficiently.
