No sooner was the marriage solemnized between Christ and his church by the conversion of the Jews than the glorious head and husband of the church is called out to a new expedition, which seems to be the great battle that was to be fought at Armageddon, foretold Rev 16:16. And here observe,
I. The description of the great Commander, 1. By the seat of his empire; and that is heaven; his throne is there, and his power and authority are heavenly and divine. 2. His equipage: he is again described as sitting on a white horse, to show the equity of the cause, and certainty of success. 3. His attributes: he is faithful and true to his covenant and promise, he is righteous in all his judicial and military proceedings, he has a penetrating insight into all the strength and stratagems of his enemies, he has a large and extensive dominion, many crowns, for he is King of kings, and Lord of lords. 4. His armour; and that is a vesture dipped in blood, either his own blood, by which he purchased this mediatorial power, or the blood of his enemies, over whom he has always prevailed. 5. His name: The Word of God, a name that none fully knows but himself, only this we know, that this Word was God manifest in the flesh; but his perfections are incomprehensible by any creature.
II. The army which he commands (Rev 19:14), a very large one, made up of many armies; angels and saints followed his conduct, and resembled him in their equipage, and in their armour of purity and righteousness - chosen, and called, and faithful.
III. The weapons of his warfare - A sharp sword proceeding from his mouth (Rev 19:15), with which he smites the nations, either the threatenings of the written word, which now he is going to execute, or rather his word of command calling on his followers to take a just revenge on his and their enemies, who are now put into the wine-press of the wrath of God, to be trodden under foot by him.
IV. The ensigns of his authority, his coat of arms - a name written on his vesture and thigh, King of kings, and Lord of lords, asserting his authority and power, and the cause of the quarrel, Rev 19:16.
V. An invitation given to the fowls of heaven, that they should come and see the battle, and share in the spoil and pillage of the field (Rev 19:17, Rev 19:18), intimating that this great decisive engagement should leave the enemies of the church a feast for the birds of prey, and that all the world should have cause to rejoice in the issue of it.
VI. The battle joined. The enemy falls on with great fury, headed by the beast, and the kings of the earth; the powers of earth and hell gathered, to make their utmost effort, Rev 19:19.
VII. The victory gained by the great and glorious head of the church: The beast and the false prophet, the leaders of the army, are taken prisoners, both he who led them by power and he who led them by policy and falsehood; these are taken and cast into the burning lake, made incapable of molesting the church of God any more; and their followers, whether officers or common soldiers, are given up to military execution, and made a feast for the fowls of heaven. Though the divine vengeance will chiefly fall upon the beast, and the false prophet, yet it will be no excuse to those who fight under their banner that they only followed their leaders and obeyed their command; since they would fight for them, they must fall and perish with them. Be wise now therefore, O you kings, be instructed, you rulers of the earth; kiss the Son, lest he be angry, and you perish from the way, Psa 2:10, Psa 2:12.

That ye may eat the flesh of kings - There shall be a universal destruction; the kings, generals, captains, and all their host, shall be slain.

That ye may eat the flesh of kings,.... Of the earth, and of the whole world, who will fall in the battle at Armageddon; see Rev 16:14 and design either those antichristian kings and states, which have drunk of the wine of Rome's fornication, and will bewail the downfall of Babylon, Rev 18:3 or those Pagan kings which will be drawn in by the pope and Turk, to aid and assist in this war, or both, when, upon the defeat of them, the Christian princes will seize upon, possess, and enjoy their kingdoms and dominions, which is meant by eating their flesh; See Gill on Rev 17:16.

And the flesh of captains; of their generals, and officers under them:

and the flesh of mighty men; the common soldiers, who are so called, Jer 46:5 who will be rifled and plundered:

and the flesh of horses, and of them that sit on them; whose rich trappings and clothes will be taken away from them:

and the flesh of all men, both free and bond, both small and great; that is, the substance of all the inhabitants of the antichristian empire, both eastern and western, of whatsoever rank, state, and condition they be, Rev 13:16. The metaphors are taken from, and there is a manifest allusion to, Eze 39:17 and the whole denotes the entire slaughter and utter ruin of the whole antichristian army, and the certainty of Christ's victory over it before hand; and also the destruction of all that are the followers of antichrist, throughout his dominions, which will now wholly fall into the hands of the saints, and be enjoyed by them.

Contrast with this "supper," Rev 19:17-18, the marriage supper of the Lamb, Rev 19:9.

captains--Greek, "captains of thousands," that is, chief captains. The "kings" are "the ten" who "give their power unto the beast."

free and bond--specified in Rev 13:16, as "receiving the mark of the beast." The repetition of flesh (in the Greek it is plural: masses of flesh) five times in this verse, marks the gross carnality of the followers of the beast. Again, the giving of their flesh to the fowls to eat, is a righteous retribution for their not suffering the dead bodies of Christ's witnesses to be put in graves.
