Book of Mormon--3 Nephi 11:1-7
And now it came to pass that there were a great multitude gathered together, of the people of Nephi, round about the temple which was in the land Bountiful; and they were marveling and wondering one with another, and were showing one to another the great and marvelous change which had taken place. And they were also conversing about this Jesus Christ, of whom the sign had been given concerning his death. And it came to pass that while they were thus conversing one with another, they heard a voice as if it came out of heaven; and they cast their eyes round about, for they understood not the voice which they heard; and it was not a harsh voice, neither was it a loud voice; nevertheless, and notwithstanding it being a small voice it did pierce them that did hear to the center, insomuch that there was no part of their frame that it did not cause to quake; yea, it did pierce them to the very soul, and did cause their hearts to burn. And it came to pass that again they heard the voice, and they understood it not. And again the third time they did hear the voice, and did open their ears to hear it; and their eyes were towards the sound thereof; and they did look steadfastly towards heaven, from whence the sound came. And behold, the third time they did understand the voice which they heard; and it said unto them: Behold my Beloved Son, in whom I am well pleased, in whom I have glorified my name—hear ye him.
