يوئيل ١:١٣

The affliction is not removed by mourning and lamentation, but only through repentance and supplication to the Lord, who can turn away all evil. The prophet therefore proceeds to call upon the priests to offer to the Lord penitential supplication day and night in the temple, and to call the elders and all the people to observe a day of fasting, penitence, and prayer; and then offers supplication himself to the Lord to have compassion upon them (Joe 1:19). From the motive assigned for this appeal, we may also see that a terrible drought had been associated with the devastation by the locusts, from which both man and beast had endured the most bitter suffering, and that Joel regarded this terrible calamity as a sign of the coming of the day of the Lord. Joe 1:13. "Gird yourselves, and lament, ye priests; howl, ye servants of the altar; come, pass the night in sackcloth, ye servants of my God: for the meat-offering and drink-offering are withdrawn from the house of your God. Joe 1:14. Sanctify a fast, call out an assembly, assemble the elders, all ye inhabitants of the land, at the house of Jehovah your God, and cry to Jehovah." From what follows we must supply bassaqqı̄m (with sackcloth) to chigrū (gird yourselves). Gird yourselves with mourning apparel, i.e., put it on (see Joe 1:8). In this they are to pass the night, to offer supplication day and night, or incessantly, standing between the altar and the porch (Joe 2:17). "Servants of my God," i.e., of the God whose prophet I am, and from whom I can promise you a hearing. The reason assigned for this appeal is the same as for the lamentation in Joe 1:9. But it is not the priests only who are to pray incessantly to the Lord; the elders and all the people are to do the same. קדּשׁ צום, to sanctify a fast, i.e., to appoin…

This chapter is the description of a lamentable devastation made of the country of Judah by locusts and caterpillars. Some think that the prophet speaks of it as a thing to come and gives warning of it beforehand, as usually the prophets did of judgments coming. Others think that it was now present, and that his business was to affect the people with it and awaken them by it to repentance. I. It is spoken of as a judgment which there was no precedent of in former ages (Joe 1:1-7). II. All sorts of people sharing in the calamity are called upon to lament it (Joe 1:8-13). III. They are directed to look up to God in their lamentations, and to humble themselves before him (Joe 1:14-20).

1:13-14 The priests were to lead all the people in public rites of mourning at the Temple. Their outward actions must be matched by authentic inward change (see 2:13).
