Joel 2:15-18

15Blow the trumpet in Zion, sanctify a fast, call a solemn assembly: 16Gather the people, sanctify the congregation, assemble the elders, gather the children, and those that suck the breasts: let the bridegroom go forth of his chamber, and the bride out of her closet. 17Let the priests, the ministers of Yhwh, weep between the porch and the altar, and let them say, Spare thy people, O Yhwh, and give not thine heritage to reproach, that the heathen should rule over them: wherefore should they say among the people, Where is their God?1

18Then will Yhwh be jealous for his land, and pity his people.
