A new mishnah! Two requirements of all grain-offerings (and not only): 1. bringing near (to the altar), and 2. waving. The bringing near is only done for grain-offerings, but not all grain-offerings. The waving is not only done for grain-offerings, and not all of them, and not all of other offerings either, but for some of them. First listed are those that require drawing near and no waving. (Rabbi Shimon doesn't agree that drawing near is required of all of the grain-offerings on this list). Also, comparing these factors and what they have in common, and where they differ. Plus, a different view again by Rabbi Shimon, where he needs to find a different common denominator (which he does): the commonality or regularity in which they are brought.
