Joel 2:5-8

5As with the rumbling of chariots, they leap on the tops of the mountains, like the crackling of a flame of fire devouring the stubble, like a powerful army drawn up for battle. 6Before them peoples are in anguish; all faces grow pale. 7Like warriors they charge; like soldiers they scale the wall. They march each on his way; they do not swerve from their paths. 8They do not jostle one another; each marches in his path; they burst through the weapons and are not halted.
