Joel 1: 13 - 15
13 Gird on sackcloth and lament, O priests, wail, O ministers of the altar. Go in, pass the night in sackcloth, O ministers of my God! Because cereal offering and drink offering are withheld from the house of your God.
14 Sanctify a fast, call a solemn assembly. Gather the elders and all the inhabitants of the land to the house of the LORD your God; and cry to the LORD.
15 Alas for the day! For the day of the LORD is near, and as destruction from the Almighty it comes.
