Joseph Smith - History

As the Prophet Joseph Smith relates Moroni's appearance, He states

"In addition to these, he quoted the eleventh chapter of Isaiah, saying that it was about to be fulfilled."  (Joseph Smith—History 1:40)

The first verses of Isaiah 11 states -

"And there shall come forth a rod out of the stem of Jesse, and a Branch shall grow out of his roots:
2 And the spirit of the Lord shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the Lord;
3 And shall make him of quick understanding in the fear of the Lord: and he shall not judge after the sight of his eyes, neither reprove after the hearing of his ears..."  (Isaiah 11:1–3)

I believe this "rod" would include the Prophet Joseph Smith as well as all modern day prophets.
