Joel 2:3-5

New Catholic Bible

³ Their vanguard is a devouring fire,
    while behind them is a consuming flame.
Ahead of them the land is like the Garden of Eden,
    but behind them lies a desert waste,
    and from that army there is no escape.
⁴ They have the appearance of horses;
    like cavalry they charge.
⁵ They leap over the mountaintops
    with a deafening din like that of chariots,
like the crackling of a blazing fire
    devouring stubble,
like a mighty army
    drawn up for battle.
