Leviticus 9

From the text today it sounds as though the ceremonies surrounding the Tabernacle and the beginning of the priests' work is drawing to a close. One thing that occurred to me while reading this evening was that maybe some of the complexity in the offering system was actually God meeting a 'need' of the Israelites. When all He asked was that they follow Him out of Egypt and not worship other gods, they failed. Maybe they needed more pomp and ceremony that they could focus on. After all, they would have doubtless seen the Egyptians making all manner of sacrifices to their pantheon of gods - maybe the expectation of such things was culturally bred into them at that point. I could be completely off base here: maybe God had symbolic or other reasons for the requirements He put in place.
