Joel the Prophet
The Prophet Joel, whose name means "Yah is God," was of the tribe of Reuben, the son of Bathuel, and lived from 810 to 750 B.C. (but some say in the 7th century B.C.). His book is divided into three chapters, and is the second in order of the minor Prophets. He foretold the coming of the Holy Spirit on the day of Pentecost (Joel 2:28, and quoted by the Apostle Peter in Acts 2:17), and the saving power of the Name of our Lord Jesus Christ (Joel 2:32).

Kontakion in the First Tone
Since thou hadst seen the glory of God in the spirit, thou truly didst foreknow His divine dispensation; for as thou didst say, God's Spirit is poured forth upon all flesh that believeth in Him Who appeared to the earthborn in a servant's form and made thee wondrous for ever, O Joel, thou seer of God.
