John Gill Bible Commentary

The Lord shall send upon thee cursing,.... Which is either a general word for all that follows, or rather, since that had been expressed before in various instances, this may denote some particular judgment. Jarchi interprets it of penury, of want of all good things, extreme poverty, so as to be reduced to the utmost necessity, and as to stand in need of the common comforts and supports of life, and even to have their blessings and mercies turned into curses; the consequence of which must needs be vexation; trouble, distress, and anguish of spirit: and rebuke; this may well be considered as a rebuke and correction in Providence for sins committed, to awaken to a sense and acknowledgment of them, and to repentance for them: in all that thou settest thine hand to do; nothing done should prosper, to relieve them under their pressing wants, a curse attending all their efforts, and so sad disappointment follows; and all as a just rebuke for their many sins: and this would be their case more or less: until thou be destroyed, and until thou perish quickly; through famine, and want of the common necessaries of life; as at the sieges of Samaria and Jerusalem, by the kings of Syria, Assyria, and Babylon: because of the wickedness of thy doings, because thou hast forsaken me; their several immoralities and impieties, and particularly their idolatry, which was a forsaking the worship of the true God, and following idols; an iniquity to be punished by the judge, and of all things the most provoking to the Lord.
