Joel 2:15-17

15Blow a trumpet in Zion [warning of impending judgment], Dedicate a fast [as a day of restraint and humility], call a solemn assembly.

16Gather the people, sanctify the congregation, Assemble the elders, Gather the children and the nursing infants. Let the bridegroom come out of his room And the bride out of her bridal chamber. [No one is excused from the assembly.]

17Let the priests, the ministers of the Lord, Weep between the porch and the altar, And let them say, “Have compassion and spare Your people, O Lord, And do not make Your inheritance (Israel) an object of ridicule, Or a [humiliating] byword among the [Gentile] nations. Why should they say among the peoples, ‘Where is their God?’ ”
