Bible reference Joel army

Joel 2:2-5

A day of darkness and gloominess,
A day of clouds and thick darkness,
Like the morning clouds spread over the mountains.
A people come, great and strong,
The like of whom has never been;
Nor will there ever be any such after them,
Even for many successive generations.

A fire devours before them,
And behind them a flame burns;
The land is like the Garden of Eden before them,
And behind them a desolate wilderness;
Surely nothing shall escape them.
Their appearance is like the appearance of horses;
And like swift steeds, so they run.
With a noise like chariots
Over mountaintops they leap,
Like the noise of a flaming fire that devours the stubble,
Like a strong people set in battle array.
