Joel 2:1-3

New Catholic Bible

¹ Blow the trumpet in Zion;
    sound the alarm on my holy mountain.
Let all the inhabitants of the land tremble,
    for the day of the Lord is coming.
² A day of darkness and gloom is near,
    a day of clouds and blackness.
Like the dawn spreading over the mountains,
    a vast and powerful army approaches.
Their like has never been seen,
    nor will it ever be seen again
    in the ages to come.
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.
