Jerald Simon writes that in Moroni's concluding chapter of his book of Moroni, we find the elements of ancient covenant treaties, except in this case, like so many of the Old Testament prophets before him, Moroni's one constant hope was rooted in the latter days. Moroni had been the custodian of the plates for thirty-five years. He knew exactly how much space he had left on the plates and perhaps had been thinking for nearly twenty years about what to include in the room he had available to him.
Moroni 10 is one of the most precise scriptural chapters that has ever been written. It deals with spiritual powers and gifts available to us in mortality. Much of the plan of salvation as it pertains to this life is included. Not only are Moroni's doctrinal declarations and sacred scriptural invitations supreme, but he is also sealing the record of the plates. He is not only preparing to place the physical capstone on the sealed stone box but with his writing is symbolically placing the capstone on the covenant concepts taught on the plates from which the Book of Mormon would emanate.
The word if appears fifteen times in this chapter and in each usage is coupled with either you or ye. "If / then," which traditionally has represented covenant language, appears powerfully in verses 32 and 33 near the conclusion of the chapter. Some mention of one of the names of God appears fifty times, always in connection with you, ye, your, or yourself. The frequency with which these terms are used indicates a sacred covenant sealing taking place.
After nearly completing the covenant-contractual terms, Moroni invites us to "come unto Christ" (Moroni 10:30). He then deftly combines passages from Isaiah 52 and 54 to help us in latter-days see the three-fold mission of the Church, first introduced to us by President Spencer W. Kimball, which is: to proclaim the gospel, perfect the Saints and redeem the dead. Moroni simply uses Isaiah's phrases, "enlarge thy borders forever," "strengthen thy stakes," and "put on thy beautiful garments" (Moroni 10:31) to describe the three aspects of the work of redemption.
How then did Moroni conclude his covenant discourse? The same way Nephi, Jacob, Abinadi, and Jesus did, with echoes of Isaiah's language:
Written to the Lamanites, who are a remnant of the house of Israel; and also to Jew and Gentile. . . . Sealed by the hand of Moroni, and hid up unto the Lord, to come forth in due time by way of the Gentile. . . . Which is to show unto the remnant of the House of Israel what great things the Lord hath done for their fathers; and that they may know the covenants of the Lord, that they are not cast off forever--And also to the convincing of the Jew and Gentile that Jesus is the Christ, the Eternal God, manifesting himself unto all nations" (see Title Page).
The reader should note that Joseph Smith said that "the title-page of the Book of Mormon is a literal translation, taken from the very last leaf, on the left hand side of the collection or book of plates."
