“They Had Ministered Those Same Words Which Jesus Had Spoken-nothing Varying”

Joseph F. McConkie, Robert L. Millet
The Nephite Apostles taught the multitude, presumably particularly those who had not been present for the Savior’s previous appearance those things they had learned from Jesus earlier. They did not editorialize or give private interpretation, but as the Savior had commanded, taught only that gospel he had delivered (see commentary on 3 Nephi 11:39-40).
