Joel 2:10

Verse 10

The earth shall quake - the heavens shall tremble - Poetical expressions, to point out universal consternation and distress. The earth quaked to see itself deprived of its verdure; the heavens trembled to find themselves deprived of their light.

The sun and the moon shall be dark - Bochart relates that "their multitude is sometimes so immense as to obscure the heavens for the space of twelve miles!" - Ibid. p. 479.
