In Ether 13:3–11, what did Moroni want us to see? Here he talks about Ether seeing the future: the days of Christ, the New Jerusalem, the millennial material, a remnant of Lehi’s posterity being preserved. The survival of the remnant was important to Moroni because these were his people. They were his enemies, but they are from the household of Lehi. In Ether 13:11, Moroni wanted us to know that the fulfilling of the covenant with Abraham applied to the Lamanite remnant because they are a part of the House of Israel. The purpose of the Book of Mormon, as indicated in the Title Page, is that we will remember the covenant.
