Joel 1
13 Ref Put haircloth round you and give yourselves to sorrow, you priests; give cries of grief, you servants of the altar: come in, and, clothed in haircloth, let the night go past, you servants of my God: for the meal offering and the drink offering have been kept back from the house of your God.
14 Ref Let a time be fixed for going without food, have a holy meeting, let the old men, even all the people of the land, come together to the house of the Lord your God, crying out to the Lord.
