Matthew Poole and continuators on Joel 1:11

11 Be ye ashamed, O ye husbandmen : howl, O ye vine-dressers , for the wheat, and for the barley; because the harvest of the field is perished .

Some read it assertively, the Husbandmen are ashamed, and as to matter of fact, 'tis true, they were ashamed, but the Imperative Mood, or by way of Exhortation it better will suit the Context; They are now called upon to blush, repent and search into the cause of this barrenness, and loss of their labour in plowing, sowing and manuring their Tillage, the Prophet aims at this principally, to bring them, as well as the Priests to Repentance.

A sort of men so well known with that people, as Gardiners are with us, men whose work was to plant, water, prune and manage Vineyards, and whose labour (unless for sin blasted) did usually succeed to a great increase.

Your sins have brought upon you this woful scarcity, your harvest in which you expected your labours and cares should be recompenced is perished, quite destroy'd, as the word imports. This is just cause why you O Husbandmen should lament and farther enquire why God is so displeased with you.
