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.

This perhaps implies that in Am 5:18 their ironical desire for the day of the Lord was as if it would be an escape from existing calamities. The coming of the day of the Lord would be good news to us, if true: for we have served God (that is, the golden calves). So do hypocrites flatter themselves as to death and judgment, as if these would be a relief from existing ills of life. The lion may from generosity spare the prostrate, but the bear spares none (compare Job 20:24; Isa 24:18).

leaned … on the wall—on the side wall of the house, to support himself from falling. Snakes often hid themselves in fissures in a wall. Those not reformed by God's judgments will be pursued by them: if they escape one, another is ready to seize them.
