Joel 2:1-3

New Revised Standard Version, Anglicised

2 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, it is near—
² a day of darkness and gloom,
    a day of clouds and thick darkness!
Like blackness spread upon the mountains
    a great and powerful army comes;
their like has never been from of old,
    nor will be again after them
    in ages to come.

³ Fire devours in front of them,
    and behind them a flame burns.
Before them the land is like the garden of Eden,
    but after them a desolate wilderness,
    and nothing escapes them.
