Why does Joel again appeal separately to the spiritual leaders?
Joel 1:13 (ESV)
13Put on sackcloth and lament, O priests; wail, O ministers of the altar. Go in, pass the night in sackcloth, O ministers of my God! Because grain offering and drink offering are withheld from the house of your God.
The spiritual leaders do not comprehend what is really going on, and neither are they leading the people in sorrow over that. As spiritual leaders they are to provide leadership to the people in serving God.
13 Put on sackcloth and lament, O priests; wail, O ministers of the altar. Go in, pass the night in sackcloth, O ministers of my God! Because grain offering and drink offering are withheld from the house of your God.
