“This may well be the most often-quoted messianic prophecy in scripture. It was first uttered by Moses to the children of Israel (Deuteronomy 18:15–19). Nephi quoted it to his people, Peter quoted it in his great discourse on the grounds of Herod’s temple (Acts 3:22–23), Christ quoted it to the nation of the Nephites (3 Nephi 21:11), Stephen quoted it while transfigured before the Sanhedrin (Acts 7:37), Moroni quoted it to Joseph Smith (Joseph Smith–History 1:40), and we find it referred to in the revelation given as a preface to the Doctrine and Covenants (D&C 1:14) and in the revelation that was once known as its appendix (D&C 133:63).” 62
The “prophet like unto Moses” who will be raised up is the Savior himself, the Holy One of Israel. Moses was a great lawgiver; Jesus is the great Lawgiver. Moses was a great deliverer; Jesus is the great Deliverer.
