Joel 1:13-14

And also you priests, put on your robes and join the outcry. You who lead people in worship, lead them in lament. Spend the night dressed in gunnysacks, you servants of my God. Nothing’s going on in the place of worship, no offerings, no prayers—nothing. Declare a holy fast, call a special meeting, get the leaders together, Round up everyone in the country. Get them into GOD’s Sanctuary for serious prayer to GOD.
