Joel: A call to repentance

From the prophet Joel 1:13-15; 2:1-2 (circa 400 BC):

Gird yourselves and weep, O priests!
Wail, O ministers of the altar!
Come, spend the night in sackcloth,
O ministers of my God!
The house of your God is deprived
of offering and libation.
Proclaim a fast,
call an assembly;
gather the elders,
all who dwell in the land,
into the house of the LORD, your God,
and cry to the LORD!
