February 1, 2021 Bible Study Why No Yeast?

I am using the daily Bible reading schedule from “The Bible.net” for my daily Bible reading.

Today, I am reading and commenting on  Leviticus 1-4.

I find it interesting that if the grain offering was baked before being offered it was to not include any yeast.  I thought I fully understood why the Passover bread was to be made without yeast: because the Israelites did not have time to allow it to rise on the first Passover.  However, the fact that these offerings were required to be made without yeast suggests that there was more to it than that.  Unfortunately, I do not know what that something more was.  I did an Internet search on the question, but I did not consider any of the results which I found satisfactory.  I have never before given this much thought, and now it has become something to which I would really like to know the answer.
