The Holy Bible, Isaiah 40:4-5

4 Every valley shall be exalted, and every mountain and hill shall be made low: and the crooked shall be made straight, and the rough places plain:

5 And the glory of the Lord shall be revealed, and all flesh shall see it together: for the mouth of the Lord hath spoken it.

The Holy Bible, Isaiah 64:1-3

1 Oh that thou wouldest rend the heavens, that thou wouldest come down, that the mountains might flow down at thy presence,

2 As when the melting fire burneth, the fire causeth the waters to boil, to make thy name known to thine adversaries, that the nations may tremble at thy presence!

3 When thou didst terrible things which we looked not for, thou camest down, the mountains flowed down at thy presence.

The Doctrine and Covenants, Section 133:22

22 And it shall be a voice as the voice of many waters, and as the voice of a great thunder, which shall break down the mountains, and the valleys shall not be found.

The Doctrine and Covenants, Section 133:40-44

40 Calling upon the name of the Lord day and night, saying: O that thou wouldst rend the heavens, that thou wouldst come down, that the mountains might flow down at thy presence.

41 And it shall be answered upon their heads; for the presence of the Lord shall be as the melting fire that burneth, and as the fire which causeth the waters to boil.

42 O Lord, thou shalt come down to make thy name known to thine adversaries, and all nations shall tremble at thy presence—

43 When thou doest terrible things, things they look not for;

44 Yea, when thou comest down, and the mountains flow down at thy presence, thou shalt meet him who rejoiceth and worketh righteousness, who remembereth thee in thy ways.
