Joel 2:16-17

gather the people. Consecrate the congregation; assemble the elders; gather the children, even nursing infants. Let the bridegroom leave his room, and the bride her chamber. Between the vestibule and the altar let the priests, the ministers of the LORD, weep and say, “Spare your people, O LORD, and make not your heritage a reproach, a byword among the nations. Why should they say among the peoples, ‘Where is their God?’”
