Joel

We don’t know anything about the prophet Joel, other than the name of his father. It is generally believed that he prophesied in the same times as Elisha, but in Judah, whereas Elisha prophesied in the northern kingdom of Israel. There is much in this book that speaks of a future judgement of God upon the enemies of Israel and Judah, and the great and terrible Day of The Lord echoes much greater judgement than just in the days of Joel. There are aspects of this prophecy that can only refer to the Lord’s second coming, when He comes to judge the earth and establish His kingdom.

Peter quoted from Joel 2:28 on the day of Pentecost, where God had promised to pour out His Spirit on all mankind.
