Amos 5:18

That desire, scoffingly, or not believing any such day would come: the prophets had long threatened such a day, but these scoffers thought no such thing could overtake them, and if it did they would know the worst of it; alter their course they will not, whatever comes on it, and they are confident the prophets fright them with bugbears: but woe to such scoffers! The day of the Lord: see Joel 1:15, Joel 2:1 Zephaniah 1:14. To what end is it for you? what do you think to get by it? what good can you expect when darkest calamities overwhelm you? The day of the Lord is darkness; all adversity, most black and doleful, therefore called in the abstract darkness. And not light; no joy, hope, or comfort in it.
