With their own eyes

1. Mosiah 27: 18
     18 And now Alma and those that were with him fell again to the earth, for great was their astonishment; for with their own eyes they had beheld an angel of the Lord; and his voice was as thunder, which shook the earth; and they knew that there was nothing save the power of God that could shake the earth and cause it to tremble as though it would part asunder.
2. Hel. 16: 20
     20 But behold, we know that this is a wicked tradition, which has been handed down unto us by our fathers, to cause us that we should believe in some great and marvelous thing which should come to pass, but not among us, but in a land which is far distant, a land which we know not; therefore they can keep us in ignorance, for we cannot witness with our own eyes that they are true.
3. 3 Ne. 5: 17
     17 And then I do make a record of the things which I have seen with mine own eyes.
