After Zeezrom (“silver guy”) not only fails to trap Amulek and Alma, he is replaced by Antionah (“gold guy”). The names not only identify the person, but also say something about the nature of the person. Thus, even before he speaks, we understand that he will do as Zeezrom began. He will ask questions designed to entrap, not to understand.
In this case, Antionah decides to go after the statement that all should rise from the dead to become immortal. He uses scripture to show that Adam and Eve were forbidden access to the Tree of Life after they were driven from the Garden, precisely so that they could not live forever. Therefore, Antionah suggests that what Alma says contradicts the scriptures.
