Joel 2:2-3

2A day of 1darkness and gloom, A day of clouds and thick darkness. As dawn is spread over the mountains, So there is a 2great and mighty people; There has 3never been anything like it, Nor will there be again after it To the years of many generations.3A 4fire consumes before them, And behind them a flame devours. The land is 5like the Garden of Eden before them, But a 6desolate wilderness behind them, And nothing at all escapes them.
