Parallel
Joel 2:5
Brenton's English Septuagint · Berean Standard Bible
As the sound of chariots on the tops of mountains shall they leap, and as the sound of a flame of fire devouring stubble, and as a numerous and strong people setting themselves in array for battle.
With a sound like that of chariots they bound over the mountaintops, like the crackling of fire consuming stubble, like a mighty army deployed for battle.
