Moses is mentioned by name seventy-five times in the Book of Mormon: the dividing of the Red Sea ; smiting the rock to obtain water for the Israelites ; deliverance of Israel from Egypt ; his countenance while on the mount ; his prophecies of the coming of the Messiah ; his references to the Son of God ; the lifting of the serpent as a type of the Savior ; and many other references. A major theme in the Book of Mormon is the fulfillment of the Law of Moses through the ministry and Atonement of the Savior. Concerning this, the resurrected Lord spoke to the Saints in Bountiful.
Behold, I say unto you that the law is fulfilled that was given unto Moses.
Behold, I am he that gave the law, and I am he who covenanted with my people Israel; therefore, the law in me is fulfilled, for I have come to fulfil the law; therefore it hath an end.
Behold, I do not destroy the prophets, for as many as have not been fulfilled in me, verily I say unto you, shall all be fulfilled.
And because I said unto you that old things have passed away, I do not destroy that which hath been spoken concerning things which are to come.
For behold, the covenant which I have made with my people is not all fulfilled; but the law which was given unto Moses hath an end in me.
