Brief Summary: A terrible plague of locusts is followed by a severe famine throughout the land. Joel uses these happenings as the catalyst to send words of warning to Judah. Unless the people repent quickly and completely, enemy armies will devour the land as did the natural elements.
Ginamit ni Joel ang mga pangyayaring ito upamg ipahayag ang babala ng Diyos sa Juda. Malibang magsisi agad at ng buong katapatan ang mga tao, sila ay sasalakayin ng mga kaaway at sasalantain ang lupain na gaya ng mga elemento.
