9. A prophet of Jehovah and writer of the Bible book bearing his name. He was the son of Pethuel.​—Joe 1:1; see JOEL, BOOK OF.

An inspired book of the Hebrew Scriptures written by “Joel the son of Pethuel.” (Joe 1:1) Virtually nothing is known about this prophet’s life. From his references to Judah, Jerusalem, and Jehovah’s house there, it may be inferred that he prophesied in Judah and perhaps resided in Jerusalem. (1:9, 14; 2:17, 32; 3:1, 2, 16-20) The fact that he mentioned “the low plain of Jehoshaphat” (3:2, 12) implies that he wrote his book after Jehovah’s great victory on behalf of King Jehoshaphat. But the exact period involved is in question.
