Amulek declares: “I will testify unto you of myself that these things are true.” The phrase “of myself” refers to his personal understanding. He is not teaching something only because he has heard if from others, but because he, himself, knows it. In this, he echoes Alma’s teaching in Alma 5:46: “I have fasted and prayed many days that I might know these things of myself. And now I do know of myself that they are true; for the Lord God hath made them manifest unto me by his Holy Spirit.” Amulek is not teaching because Alma said so, but because Amulek, as did Alma, had learned it for himself. Thus, he can be the second witness to the truthfulness of what Alma taught.
