Joel the ProphetJoel - Joel is considered one of the minor prophets (not because of his importance in Israel's history, but simply because of the short length of his book).  Outside of his book, he is not mentioned anywhere else, except for the one time he is quoted by the Apostle Peter (Acts 2:17-21).  And there are no clues within the Book of Joel as to when he lived; but many Biblical scholars place him in the tier of early prophets based on his warnings of approaching doom.

 

"Let all the inhabitants of the land tremble,
For the day of the Lord is coming;
Surely it is near,
A day of darkness and gloom,
A day of clouds and thick darkness.
As the dawn is spread over the mountains,
So there is a great and mighty people;
There has never been anything like it,
Nor will there be again after it
To the years of many generations.
A fire consumes before them
And behind them a flame burns.
The land is like the garden of Eden before them
But a desolate wilderness behind them,
And nothing at all escapes them." (Joel 2:1-3, NASB)
