Isaiah 64:1-3

1Oh, that You would tear open the heavens and come down, That the mountains might quake at Your presence—

2As [sure as] fire kindles the brushwood, as fire causes water to boil— To make Your name known to Your adversaries, That the nations may tremble at Your presence!

3When You did awesome and amazing things which we did not expect, You came down [at Sinai]; the mountains quaked at Your presence.
