Mormon provided the text that ended the previous chapter. He provides a simple sentence that narrates the beginning of this inserted sermon. Since Mormon told us that there was an attempt to put Alma in prison and that there were many things written that he didn’t use for his abridgment, we should assume that this sermon took place at a different time, perhaps at a different place. What Mormon has done is give us the first witness, Alma, and now gives Amulek as the second witness. Thus, Mormon shows conformance to the Deuteronomic law of witnesses.
