I'm pretty sure the book of Numbers could be chopped down to 3-5 chapters. But no, we have to repeat everything.
Numbers 28 is about offerings. The same offerings. They haven't changed. I don't even know what to say any more. Just burn lots of animals and you should be covered.
Numbers 29 is about various feasts and celebrations that have already been talked about. Does anyone in the Jewish community still do this? The feast of the tabernacle alone kills hundreds of animals. The first day of the feast of the tabernacles you sacrifice 13 bulls, the second day 12, the third day 11 and so on until the seventh day. That is 70 bulls, and that's not counting any of the other animals. I don't imagine that even huge ranch owners could afford to sacrifice 70 bulls per year (and keep in mind that this is only one of many festivals). Let's hope this is for the entire Israelite community and not per tribe.
Numbers 30 is mildly interesting. If a man takes a vow to God he mustn't break it no matter what. If a woman makes a vow, on the other hand, and her husband (or father) forbids her from doing it, then it's as if she hasn't made a vow. Really bible? Sexist much? Oh wait, yes, the bible is pretty much a sexist manifesto. I keep forgetting.
