Joel 1:13

The prophet turned again to the priests (cf. Joel 1:9) and urged them to lament in sackcloth because the grain and wine used in their offerings were no longer available. Joel’s second call to the priests underlines the tragedy of curtailed worship in Judah’s life. Since there were no offerings to bring to the Lord, the nation could not approach Him as He had directed at the very time she needed Him most. This closing reference to priests in this section contrasts with the opening reference to drunkards (Joel 1:5-7), from the most ungodly to the most godly (ideally). This merism has the effect of including all the citizens of Judah in Joel’s call. Joel’s reference to "my God" and "your God" in this verse ties him closely to the priests; their concerns and their relationship to Yahweh were ideally the same.
