We must translate the numbers of the census into the needs of the real live population. And that is why the Torah lists the identical offering of each tribal representative. One of the results of taking a census is the tendency to think in statistics instead of relating to people. The beginning of Parashat Naso provides for the necessary counting of the people. The end of Parashat Naso reminds us that people are not numbers.
People are people, and deserve individual attention even when such attention appears redundant.
By reading the list over and over we learn that our individual offering to society matters. We are not the same as our neighbor, even though we may be working for the same goals as our neighbor and even engaged in the same tasks as our neighbor. Each tribe matters, each family matters, each individual matters, each offering matters.
