1. We continue the Exodus imagery, explicitly comparing Abinadi to Moses.
2. This idea that Abinadi expresses that things that we do now are a "type and a shadow" of things to come is at the heart of the religion of the visionary men. This is the lesson of the Small Plates of Nephi: they saw the temple rites that they practiced, which are confused and half-reported in the OT, as foreshadowing the Lord's future incarnations and the redemption of Israel.
3. I like that Abinadi describes the law of Moses as a law of "performances". It makes me think of a play, and the temple ordinances are all -- and were all -- a kind of prophetic theater. The performances keep people "in remembrance"(cf. Leviticus 24 and Luke 22).
4. This reads like a thumbnail interpretation of the Day of Atonement rite, except possibly the resurrection of the dead reference. I'll have to think about that one.
