Psalm 97:5
3 Fire goes before him; on every side it burns up his enemies. 4 His lightning bolts light up the world; the earth sees and trembles. 5 The mountains melt like wax before the Lord, before the Lord of the whole earth. 6 The sky declares his justice, and all the nations see his splendor.
1 Enoch 1:6
5 Everyone will be struck with fear and the Watchers will tremble, and great fear and trembling will grip them to the ends of the earth. 6 The high mountains will shake, the hills will be leveled, and they will melt like wax before the fire 7 The earth will be completely torn apart, and everything on it will perish, and there will be judgment upon all people.
Notes and References
"... 1 Enoch 1:6-7 ... These verses depict the total distortion and disintegration of the earth in the presence of the divine Judge. Verse 6 reflects a traditional element in the descriptions of the events associated with a theophany: the mountains quake, fall, and break apart. The picture is enhanced by the simile of the mountains melting like wax before the fire. This image, which suggests an erupting volcano, probably derives from Micah 1:3-4, whose motifs were temporarily abandoned after verse 4. The image appears also in Psalm 97:5; Isaiah 64:1 LXX; Judith 16:15; compare Nahum 1:5. The text describes the mightiest structures on earth - the everlasting mountains and hills - disintegrating helplessly before the presence of 'the Great Holy One' ..."
