Joel 1:13, 14

Put on sackcloth, you priests, and mourn; wail, you who minister before the altar. Come, spend the night in sackcloth, you who minister before my God; for the grain offerings and drink offerings are withheld from the house of your God.

Declare a holy fast; call a sacred assembly. Summon the elders and all who live in the land to the house of the LORD your God, and cry out to the LORD.
