What an Offer!
The end of the parsha is a tremendously lengthy discussion of the different sacrifices that we must offer to Hashem. Of course, we must wonder why this discussion is mentioned at this point? Rabbeinu Bachya explains that when Moshe realized that he was not going into Eretz Yisroel he needed to inform them of these important matters, attending to the service in the Mishkan and later the Beis Hamikdash.
