The Book of Joel was written by the prophet Joel, who father’s name was Pethuel. Although there are twelve other men with the same name mentioned in the Bible, we can’t identify them with the author of this book.
In fact, all we know about Joel is what’s found within the book itself. We do know that His name means, ‘The Lord is God’, and he was a very powerful prophet who boldly spoke the word of God.
"Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls."
