I testify of myself

1. Alma 34: 8
     8 And now, behold, I will testify unto you of myself that these things are true. Behold, I say unto you, that I do know that Christ shall come among the children of men, to take upon him the transgressions of his people, and that he shall atone for the sins of the world; for the Lord God hath spoken it.
2. Hel. 7: 29
     29 Behold now, I do not say that these things shall be, of myself, because it is not of myself that I know these things; but behold, I know that these things are true because the Lord God has made them known unto me, therefore I testify that they shall be.
