A Commentary, Critical, Practical, and Explanatory on the Old and New Testaments, by Robert Jamieson, A.R. Fausset and David Brown  at sacred-texts.com
isa 25:1CONTINUATION OF THE TWENTY-FOURTH CHAPTER. THANKSGIVING FOR THE OVERTHROW OF THE APOSTATE FACTION, AND THE SETTING UP OF JEHOVAH'S THRONE ON ZION. (Isa 25:1-12)
wonderful-- (Isa 9:6).
counsels of old-- (Isa 42:9; Isa 46:10). Purposes planned long ago; here, as to the deliverance of His people.
truth--Hebrew, Amen; covenant-keeping, faithful to promises; the peculiar characteristic of Jesus (Rev 3:14).
isa 25:2a city . . . heap--Babylon, type of the seat of Antichrist, to be destroyed in the last days (compare Jer 51:37, with Rev. 18:1-24, followed, as here, by the song of the saints' thanksgiving in Rev. 19:1-21). "Heaps" is a graphic picture of Babylon and Nineveh as they now are.
palace--Babylon regarded, on account of its splendor, as a vast palace. But MAURER translates, "a citadel."
of strangers--foreigners, whose capital pre-eminently Babylon was, the metropolis of the pagan world. "Aliens from the commonwealth of Israel, strangers from the covenants of promise" (Isa 29:5; Eph 2:12; see in contrast, Joe 3:17).
never be built-- (Isa 13:19-20, &c.).
isa 25:3strong people--This cannot apply to the Jews; but other nations on which Babylon had exercised its cruelty (Isa 14:12) shall worship Jehovah, awed by the judgment inflicted on Babylon (Isa 23:18).
city--not Babylon, which shall then be destroyed, but collectively for the cities of the surrounding nations.
isa 25:4the poor . . . needy--the Jews, exiles from their country (Isa 26:6; Isa 41:17).
heat--calamity (Isa 4:6; Isa 32:2).
blast--that is, wrath.
storm--a tempest of rain, a winter flood, rushing against and overthrowing the wall of a house.
isa 25:5Translate, "As the heat in a dry land (is brought down by the shadow of a cloud, so) thou shalt bring down the tumult (the shout of triumph over their enemies) of strangers (foreigners); and as the heat by the shadow of the cloud (is brought low), so the branch (the offspring) of the terrible ones shall be brought low." PARKHURST translates the Hebrew for "branch," the exulting song. JEROME translates the last clause, "And as when the heat burns under a cloud, thou shalt make the branch of the terrible ones to wither"; the branch withering even under the friendly shade of a cloud typifies the wicked brought to ruin, not for want of natural means of prosperity, but by the immediate act of God.
isa 25:6in this mountain--Zion: Messiah's kingdom was to begin, and is to have its central seat hereafter, at Jerusalem, as the common country of "all nations" (Isa 2:2, &c.).
all people-- (Isa 56:7; Dan 7:14; Luk 2:10).
feast--image of felicity (Psa 22:26-27; Mat 8:11; Luk 14:15; Rev 19:9; compare Psa 36:8; Psa 87:1-7).
fat things--delicacies; the rich mercies of God in Christ (Isa 55:2; Jer 31:14; Job 36:16).
wines on the lees--wine which has been long kept on the lees; that is, the oldest and most generous wine (Jer 48:11).
marrow--the choicest dainties (Psa 63:5).
well refined--cleared of all dregs.
isa 25:7face of . . . covering--image from mourning, in which it was usual to cover the face with a veil (Sa2 15:30). "Face of covering," that is, the covering itself; as in Job 41:13, "the face of his garment," the garment itself. The covering or veil is the mist of ignorance as to a future state, and the way to eternal life, which enveloped the nations (Eph 4:18) and the unbelieving Jew (Co2 3:15). The Jew, however, is first to be converted before the conversion of "all nations"; for it is "in this mountain," namely, Zion, that the latter are to have the veil taken off (Psa 102:13, Psa 102:15-16, Psa 102:21-22; Rom 11:12).
isa 25:8Quoted in Co1 15:54, in support of the resurrection.
swallow up . . . in victory--completely and permanently "abolish" (Ti2 1:10; Rev 20:14; Rev 21:4; compare Gen 2:17; Gen 3:22).
rebuke--(Compare Mar 8:38; Heb 11:26).
isa 25:9And it shall be said in that day, &c.--"After death has been swallowed up for ever, the people of God, who had been delivered from the hand of death, shall say to the Lord, Lo, this is our God, whom unbelievers regarded as only a man" [JEROME]. "The words are so moulded as to point us specially to the person of the Son of God, who 'saves' us; as He vouchsafed to Israel temporal saving, so to His elect He appears for the purpose of conferring eternal salvation" [VITRINGA]. The Jews, however, have a special share in the words, This is our God (see on Isa 25:6).
we have waited--"Waited" is characteristic of God's people in all ages (Gen 49:18; Tit 2:13).
we will be glad and rejoice in his salvation--compare Psa 118:24, which refers to the second coming of Jesus (compare Psa 118:26, with Luk 13:35).
isa 25:10rest--as its permanent protector; on "hand" in this sense; compare Ezr 7:6, Ezr 7:28.
Moab--while Israel is being protected, the foe is destroyed; Moab is the representative of all the foes of God's people.
under him--Rather, "in his own place" or "country" (Exo 10:23; Exo 16:29).
for the dunghill--Rather, "in the water of the dung heap," in which straw was trodden to make it manure (Psa 83:10). HORSLEY translates either, "in the waters of Madmenah," namely, for the making of bricks; or as the Septuagint, "as the threshing-floor is trampled by the corn-drag" (see Margin; Mic 4:11-13).
isa 25:11he--Jehovah shall spread His hands to strike the foe on this side and on that, with as little effort as a swimmer spreads forth his arms to cleave a passage through the water [CALVIN]. (Zac 5:3). LOWTH takes "he" as Moab, who, in danger of sinking, shall strain every nerve to save himself; but Jehovah (and "he") shall cause him to sink ("bring down the pride" of Moab, Isa 16:6).
with the spoils of . . . hands--literally, "the craftily acquired spoils" of his (Moab's) hands [BARNES]. Moab's pride, as well as the sudden gripe of his hands (namely, whereby he tries to save himself from drowning) [LOWTH]. "Together with the joints of his hands," that is, though Moab struggle against Jehovah hand and foot [MAURER].
isa 25:12fortress--the strongholds of Moab, the representative of the foes of God's people [BARNES]. Babylon [MAURER]. The society of infidels represented as a city (Rev 11:8).
As the overthrow of the apostate faction is described in the twenty-fifth chapter, so the peace of the faithful is here described under the image of a well-fortified city.
