Helaman 12:15

and thus according to his word, the earth goeth back, and it appeareth unto man that the sun standeth still; yea, and behold, this is so: for sure it is the earth that moveth, and not the sun.

When he commands, the earth goes backward. To people it looks like the sun stands still. This is true. It’s the earth that moves, not the sun.

According to his word, the earth moves backward, and it looks to us like the sun stands still. And that’s exactly what happens—because it’s the earth that moves, not the sun.
