Joel 1:8

The vicious and wicked among the Jews were alarmed and threatened in the former part of the chapter; now the prophet bespeaks the good and godly among them to prepare for mournful times. Lament: this is minatory, and threatens calamitous times shall come, as well as directive, what to do when they are come; when God calls for weeping we must not rejoice. Like a virgin: this tells us to whom the prophet directs this part of his sermon, it is to those who amidst the Jews were like chaste and modest virgins, whose heart was fixed on one, her own, her chosen beloved husband. Girded with sackcloth: in deep mournings the people of those countries did use sackcloth in their mourning habit, and wore it girded close to their skin. For the husband of her youth; either married to her in youth, or espoused to her, but snatched away from her by an untimely death, which she doth most bitterly lament.
