Helaman 14:23

And behold there shall be great tempests, and there shall be many mountains laid low, like unto a valley, and there shall be many places, which are now called valleys, which shall become mountains, whose height thereof is great.

“There will be great storms. Many mountains will become flat like valleys. Many places that are valleys now will become very tall mountains.”

“There will be violent storms. Many mountains will be flattened into valleys. Many places that are valleys now will become towering mountains.”
