And they cast dust on their heads - A common sign of lamentation and mourning among the Orientals. See the notes on Job 2:12.

By reason of her costliness - The word rendered "costliness" - τιμιότητος timiotētos - means, properly, "preciousness, costliness"; their magnificence, costly merchandise. The luxury of a great city enriches many individuals, however much it may impoverish itself.

For in one hour is she made desolate - So it seemed to them. See the notes on Revelation 18:17.

They cast dust on their heads - They showed every sign of the sincerest grief. The lamentation over this great ruined city, Revelation 18:9-19, is exceedingly strong and well drawn. Here is no dissembled sorrow; all is real to the mourners, and affecting to the spectators.

And they cast dust on their heads,.... As the seafaring men on account of Tyre, Ezekiel 27:30 this was a gesture used in mourning when persons were in afflicted and distressed circumstances, denoting disorder, confusion, and debasement; see Joshua 7:6

and cried, weeping and wailing, saying, alas, alas! that great city; as in Revelation 18:10 so it was once, though now in flames:

wherein were made rich all that had ships in the sea; not only the merchants of the earth, as in Revelation 18:3 the cardinals, archbishops, and bishops, but the governors of religious houses; these accumulated great wealth to themselves, and got the best of lands into their possession for the use and support of their abbeys and monasteries:

by reason of her costliness; or costly things; pardons, indulgences, absolution, saying Mass, and praying souls out of purgatory, all which are costly, and hereby these traders have been enriched; and now the remembrance of these things, of which they will be deprived, will affect and grieve them, as well as the suddenness of Rome's ruin:

for in one hour is she made desolate; her judgment come, and her riches come to nought, Revelation 18:10.

Cast dust on their heads

Compare Ezekiel 27:30. See on Luke 10:13.

And they cast dust on their heads, and cried, weeping and wailing, saying, Alas, alas that great city, wherein were made rich all that had ships in the sea by reason of her costliness! for in one hour is she made desolate.

18:15-19 The merchants of these things... shall stand afar off. The lamentation of the kings over the fall of the city has been given in Re 18:9-14. The lamentation of the merchants is now given. They are also represented as standing afar off. With them join the shipmasters and mariners who have been engaged in her trade. These all mourn because their profits from her are brought to an end.

18:19 And they cast dust on their heads - As mourners. Most of the expressions here used in describing the downfall of Babylon are taken from Ezekiel's description of the downfall of Tyre, Ezek 26:1 - Eze 28:19.

19. wailing-"mourning."

that had ships-A, B, and C read, "that had their ships": literally, "the ships."

costliness-her costly treasures: abstract for concrete.

18:9-19 The mourners had shared Babylon's sensual pleasures, and gained by her wealth and trade. The kings of the earth, whom she flattered into idolatry, allowing them to be tyrannical over their subjects, while obedient to her; and the merchants, those who trafficked for her indulgences, pardons, and honours; these mourn. Babylon's friends partook her sinful pleasures and profits, but are not willing to share her plagues. The spirit of antichrist is a worldly spirit, and that sorrow is a mere worldly sorrow; they do not lament for the anger of God, but for the loss of outward comforts. The magnificence and riches of the ungodly will avail them nothing, but will render the vengeance harder to be borne. The spiritual merchandise is here alluded to, when not only slaves, but the souls of men, are mentioned as articles of commerce, to the destroying the souls of millions. Nor has this been peculiar to the Roman antichrist, and only her guilt. But let prosperous traders learn, with all their gains, to get the unsearchable riches of Christ; otherwise; even in this life, they may have to mourn that riches make to themselves wings and fly away, and that all the fruits their souls lusted after, are departed from them. Death, at any rate, will soon end their commerce, and all the riches of the ungodly will be exchanged, not only for the coffin and the worm, but for the fire that cannot be quenched.
