Redundant?

Public Announcement: Due to uncontrollable factors I have not been able to have internet access as much as I would like. This current situation should be in affect till Monday. Then it will be a new day, oh yes -a new day, for there will be wireless in my apartment. The only downside is I won’t have an excuse for not posting more often. Now on with my thought/question:

For the past three days we’ve been reading Numbers 7, which is 89 verses, in staff meeting. The majority of the chapter goes something like this:

"The one who brought his offering on the first day was Nahshon son of Amminadab of the tribe of Judah.
His offering was one silver plate weighing a hundred and thirty shekels, and one silver sprinkling bowl weighing seventy shekels, both according to the sanctuary shekel, each filled with fine flour mixed with oil as a grain offering; 14 one gold dish weighing ten shekels, filled with incense; 15 one young bull, one ram and one male lamb a year old, for a burnt offering; 16 one male goat for a sin offering; 17 and two oxen, five rams, five male goats and five male lambs a year old, to be sacrificed as a fellowship offering. This was the offering of Nahshon son of Amminadab." (Numbers 7:12-17)

This pattern continues for the next 80 verses, then the author sums up the totals of all the gifts brought. Why didn’t they just say that in the first place? I realize that all Scripture is God-breathed and useful…but the usefulness of this chapter is past my current understanding. I really don’t see the value or repeating 12 times the same information. Anyone care to explain? (please do it with grace)
