Woe unto you that {k} desire the day of the LORD! to what end is it for you? the day of the LORD is darkness, and not light.

(k) He speaks in this way because the wicked and hypocrites said they were content to endure God's judgments, whereas the godly tremble and fear; Jer 30:7, Joe 2:2,11, Zep 1:15.

Wesley's Notes

5:18 That desire - Scoffingly, not believing any such day would come. To what end - What do you think to get by it? Is darkness - All adversity, black and doleful. Not light - No joy, or comfort an it.

Jamieson-Fausset-Brown Bible Commentary

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.

Matthew Henry's Concise Commentary

5:18-27 Woe unto those that desire the day of the Lord's judgments, that wish for times of war and confusion; as some who long for changes, hoping to rise upon the ruins of their country! but this should be so great a desolation, that nobody could gain by it. The day of the Lord will be a dark, dismal, gloomy day to all impenitent sinners. When God makes a day dark, all the world cannot make it light. Those who are not reformed by the judgments of God, will be pursued by them; if they escape one, another stands ready to seize them. A pretence of piety is double iniquity, and so it will be found. The people of Israel copied the crimes of their forefathers. The law of worshipping the Lord our God, is, Him only we must serve. Professors thrive so little, because they have little or no communion with God in their duties. They were led captive by Satan into idolatry, therefore God caused them to go into captivity among idolaters.
