Joel 2:16

gather the people, for a great meeting of worship and supplication; sanctify the congregation, so that no one would be Levitically unclean; assemble the elders, the aged people of the congregation; gather the children and those that suck the breast, for no one is to be omitted in this great appeal for mercy, since all of them, from the smallest to the greatest, were guilty; let the bridegroom go forth of his chamber and the bride out of her closet, where they were preparing for the coming wedding. The fact that even infants in arms and bride and groom were included in the appeal of the prophet shows that the guilt was universal and beyond excuse.
