18. Woe unto you who do not scruple to say in irony, "We desire that the day of the Lord would come," that is, "Woe to you who treat it as if it were a mere dream of the prophets" (Isa 5:19; Jer 17:15; Eze 12:22).
      to what end is it for you!--Amos taking their ironical words in earnest: for God often takes the blasphemer at his own word, in righteous retribution making the scoffer's jest a terrible reality against himself. Ye have but little reason to desire the day of the Lord; for it will be to you calamity, and not joy.
