Revelation 18:21
Then a mighty angel picked up a stone the size of a great millstone and cast it into the sea, saying: "With such violence the great city of Babylon will be cast down, never to be seen again.
Then a mighty angel picked up a stone the size of a great millstone

God commissions a mighty angel to portray the certainty and weight of His judgment. A great millstone was an immense stone used in grinding grain, too heavy for ordinary handling and devastating in its impact. The image recalls Jeremiah’s command to bind a stone to the scroll containing Babylon’s judgments and cast it into the Euphrates, declaring that Babylon would sink and not rise again (Jeremiah 51:63–64).

Mat 18:6 But if anyone causes one of these little ones…
Mrk 9:42 But if anyone causes one of these little ones…
Luk 17:2 It would be better for him to have a millstone…

and cast it into the sea,

The angel’s action provides a visible sign of Babylon’s sudden and irreversible overthrow. The sea, a place of chaos and engulfing power, receives the stone without possibility of recovery. God once cast Pharaoh’s forces into the sea when He delivered Israel (Exodus 15:4–5); now He brings final judgment upon the world power that has exalted wealth, idolatry, immorality, and persecution of His people.

Jer 51:63-64 When you finish reading this scroll, tie a stone to it…
Jon 1:15 Then they picked up Jonah and cast him into the sea,…

saying: “With such violence the great city of Babylon will be cast down,

Babylon’s fall will not result merely from economic collapse or political transition but from the direct judgment of God. The city that ruled the kings and commerce of the earth will be violently removed because it corrupted the nations and shed the blood of saints and prophets. Isaiah and Jeremiah foretold the downfall of ancient Babylon, and their prophecies foreshadow the final destruction of the end-time Babylon described in Revelation.

Jer 51:8 Suddenly Babylon has fallen and been shattered.…
Isa 21:9 “Look, here come the riders, horsemen in pairs.”…
Jer 51:58 This is what the LORD of Hosts says: “Babylon’s thick walls……

never to be seen again.

Babylon will not recover, rebuild, or regain influence. Its destruction closes the era of human rebellion organized against God and clears the way for Christ’s righteous kingdom. The permanence of Babylon’s judgment stands in sharp contrast to the eternal city of God, the New Jerusalem, which will endure forever.

Ezk 26:21 I will make you an object of horror, and you will be no more…
Isa 13:20 She will never be inhabited or settled…
Jer 51:62 O LORD, You have promised to cut off this place…

Death Swallowed up in victory
Then shall be brought to pass the saying that is written, Death is swallowed up in victory! D eath, simply considered, is no more than the cessation of life --that which was once living, lives no longer. But it has been the general, perhaps the universal custom of mankind, to personify it. Imagination gives death a formidable appearance, arms it with a dart, sting or scythe, and represents it as an active, inexorable and invincible reality. In this view death is a great devourer; with his iron tongue

The Northern Iron and the Steel
That being the literal meaning, we shall draw from our text a general principle. It is a proverbial expression, no doubt, and applicable to many other matters besides that of the prophet and the Jews; it is clearly meant to show, that in order to achieve a purpose, there must be a sufficient force. The weaker cannot overcome the stronger. In a general clash the firmest will win. There must be sufficient firmness in the instrument or the work cannot be done. You cannot cut granite with a pen-knife,

War! War! War!
At the present crisis, the minds of men are exceedingly agitated with direful prospects of a terrible struggle. We know not whereunto this matter may grow. The signs of the times are dark and direful. We fear that the vials of God's wrath are about to be poured out, and that the earth will be deluged with blood. As long as there remains a hope, let us pray for peace, nay, even in the time of war let us still beseech the throne of God, crying, that he would "send us peace in our days." The war will

"If So be that the Spirit of God Dwell in You. Now if any Man have not the Spirit of Christ, He is None of His. "
Rom. viii. 9.--"If so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his." "But will God in very deed dwell with men on the earth?" 2 Chron. vi. 18. It was the wonder of one of the wisest of men, and indeed, considering his infinite highness above the height of heavens, his immense and incomprehensible greatness, that the heaven of heavens cannot contain him, and then the baseness, emptiness, and worthlessness of man, it may be a wonder to the

E.W. Bullinger—Commentary on Revelation

The Sun Rising Upon a Dark World
The people that walked in darkness have seen a great light: they that dwell in the land of the shadow of death, upon then hath the light shined. C ontrasts are suited to illustrate and strengthen the impression of each other. The happiness of those, who by faith in MESSIAH, are brought into a state of peace, liberty, and comfort, is greatly enhanced and heightened by the consideration of that previous state of misery in which they once lived, and of the greater misery to which they were justly exposed.
John Newton—Messiah Vol. 1

Covenanting Adapted to the Moral Constitution of Man.
The law of God originates in his nature, but the attributes of his creatures are due to his sovereignty. The former is, accordingly, to be viewed as necessarily obligatory on the moral subjects of his government, and the latter--which are all consistent with the holiness of the Divine nature, are to be considered as called into exercise according to his appointment. Hence, also, the law of God is independent of his creatures, though made known on their account; but the operation of their attributes

OF THE HOUSE OF THE FOREST OF LEBANON. ADVERTISEMENT BY THE EDITOR. That part of Palestine in which the celebrated mountains of Lebanon are situated, is the border country adjoining Syria, having Sidon for its seaport, and Land, nearly adjoining the city of Damascus, on the north. This metropolitan city of Syria, and capital of the kingdom of Damascus, was strongly fortified; and during the border conflicts it served as a cover to the Assyrian army. Bunyan, with great reason, supposes that, to keep
