Are the ministering priests in Malachi suffering because the people have not brought the tithes?
Not necessarily. While the priests are mentioned as poor and needing the tithe in Deuteronomy 12:18; 14:29 and 26:12-13, they are not included in the list of Malachi 3:5. The ministers, not the people, are the cursed robbers in most of Malachi. If there is a correlation in Malachi to modern preachers, it might be that they are taking money from the people under one pretense and are keeping much of it for themselves, instead of helping the poor.
