Except the Lord of hosts had left unto us Here he concludes what he had formerly declared concerning God's chastisements, that the desolation which shall take place -- or rather which is present, and which they now behold -- may be compared to the destruction of Sodom, were it not that the Lord snatched as it were from the burning a very small remnant. And this verse confirms what I formerly said, that the Prophet's description of the calamities which had already taken place is interwoven with those events which were immediately at hand, as if he had said, Be not deceived by flatteries; you would be in the same condition that Sodom and Gomorrah now are, were it not that God, in compassion on you, has preserved a remnant. This agrees with the words of Jeremiah, It is of the Lord's mercies that we are not consumed. (Lamentations 3:22.) Hence we ought to observe two things. First, the Prophet here describes utter destruction; and yet, because God had to deal with his Church and his beloved people, that judgment is mitigated by special grace, so that out of the general ruin of the whole nation God rescues his people, whom he justly compares to a very small remnant. But if God punished the crimes of the Jews by such dreadful chastisements, let us consider that we may share the same fate if we imitate their rebellion: for God had set apart that nation for himself, and had distinguished them from the ordinary lot of other men. Why then should he spare us if we shall be hardened in our ungodliness and treachery? Or rather, what is likely to be the result of that mass and sink of crimes in which men throughout the whole world give way to their passions? Unquestionably it will be the same with the fate of Sodom and Gomorrah, unless his vengeance shall be restrained by a regard to that gracious covenant in which he promised that the Church shall be eternal; and this threatening, which is truly awful and alarming, is applicable to all obstinate and incurable men, whose vices no punishments can destroy or weaken. Again, we ought to observe that saying of Jeremiah, which I have already glanced at, that it must be attributed to the tender mercies of God that we are not altogether destroyed. (Lamentations 2:22.) For if We Shall Consider the vast amount Of wickedness which prevails among all classes, we shall wonder that even a single individual is left, and that all have not been removed from the land of the living; and in this way God withdraws his hand, (Ezekiel 20:22,) that there may be some Church preserved in the world. This is the reason assigned by Paul, who is the best interpreter of this passage, when, by quoting it, he represses the haughtiness of the Jews, that they may not boast of the mere name, as if it had been enough that they were descended from the fathers; for he reminds them that God could act towards them as he had formerly done towards the fathers, but that through his tender mercies a remnant shall be saved. (Romans 9:27.) And why? That the Church may not utterly perish; for it is through the favor which he bears towards it that the Lord, though our obstinacy lays him under the necessity of trying the severest judgments, still reserves some small seed. (Romans 9:29.) This statement ought to yield us powerful consolation even in those heaviest calamities in which we are apt to think that it is all over with the Church; that, though everything should go into confusion, and the world, as we say, be turned upside down, we may persevere with unshaken fortitude, and may rest assured that God will always be mindful of his Church. A very small remnant This clause may be connected either with what goes before or with what follows, and accordingly some render it, We would have been almost like Sodom. But I prefer connecting it with the former clause, so as to deduce that the number which God had reserved out of the destruction is small. Some think that: k (caph) is here used affirmatively, so as to express the matter more strongly; and I have no objection to that view, though we may take it in its natural and literal signification, as if he had said, "and that shall be a small number." This declaration ought to be carefully observed; for if the Church does not spread far and wide, men are wont to despise her. Hence it comes that hypocrites are proud of their numbers; and weak men, terrified by the pompous display of those numbers, stagger. We also learn from it that we ought not to judge by the largeness of the number, unless we choose to prefer the chaff to the wheat, because the quantity is greater; but we ought to be satisfied with knowing that, though the number of the godly be small, still God acknowledges them as his chosen people; and we ought also to call to remembrance that consolatory saying, Fear not, little flock; for it is your Father's good pleasure to give you the kingdom. (Luke 12:32.)

Except - It is owing entirely to the mercy of God, that we are not like Sodom. The prophet traces this not to the goodness of the nation, not to any power or merit of theirs, but solely to the mercy of God. This passage the apostle Paul has used in an argument to establish the doctrine of divine sovereignty in the salvation of people; see the note at Romans 9:29.
The Lord - Hebrew Yahweh. Note Isaiah 1:2.
Of hosts - צבאות tsebâ'ôth - the word sometimes translated "Sabaoth"; Romans 9:29; James 5:4. The word means literally armies or military hosts. It is applied, however, to the angels which surround the throne of God; 1-Kings 22:19; 2-Chronicles 18:18; Psalm 103:21; and to the stars or constellations that appear to be marshalled in the sky; Jeremiah 33:22; Isaiah 40:26. This host, or the "host of heaven," was frequently an object of idolatrous worship; Deuteronomy 4:19; Deuteronomy 17:3; 2-Kings 17:16. God is called Yahweh of hosts because he is at the head of all these armies, as their leader and commander; he marshals and directs them - as a general does the army under his command. 'This,' says Gesenius, 'is the most common name of God in Isaiah, and in Jeremiah, Zechariah, and Malachi. It represents him as the ruler of the hosts of heaven, that is, the angels and the stars. Sometimes, but less frequently, we meet with the appellation Yahweh, God of hosts. Hence, some suppose the expression Yahweh of hosts to be elliptical. But it is not a correct assertion that Yahweh, as a proper name, admits of no genitive. But such relations and adjuncts as depend upon the genitive, often depend upon proper names. So in Arabic, one is called Rebiah of the poor in reference to his liability.' The name is given here, because to save any portion of a nation so wicked implied the exercise of the same power as that by which he controlled the hosts of heaven.
Remnant - A small part - that which is left. It means here, that God had spared a portion of the nation, so that they were not entirely overthrown.
We should have been as Sodom - This does not refer to the character of the people, but to their destiny. If God had not interposed to save them they would have been overwhelmed entirely as Sodom was; compare Genesis 19:24-25.

The Lord of hosts "Jehovah God of hosts" - As this title of God, יהוה צבאות Yehovah tsebaoth, "Jehovah of hosts, occurs here for the first time, I think it proper to note, that I translate it always, as in this place, "Jehovah God of hosts;" taking it as an elliptical expression for יהוה אלהי צבאות Yehovah Elohey tsebaoth. This title imports that Jehovah is the God or Lord of hosts or armies; as he is the Creator and Supreme Governor of all beings in heaven and earth, and disposeth and ruleth them all in their several orders and stations; the almighty, universal Lord.
We should have been as Sodom - As completely and finally ruined as that and the cities of the plain were, no vestige of which remains at this day.

Except the LORD of hosts (p) had left to us a very small remnant, we should have been (q) as Sodom, we should have been like Gomorrah.
(p) Because he will always have a Church to call on his Name.
(q) That is, all destroyed.

Except the Lord of hosts had left unto us a very small remnant,.... This is an instance of the super abounding goodness of the Lord of hosts, as the Targum expresses it; that he should, in those very wicked and calamitous times, leave and reserve a few from being defiled with the sins of the age, and from being involved in the general calamity of it; which was true of the Christian Jews at the time of Jerusalem's destruction; for that this prophecy belongs to these times is clear from the application of it by the Apostle Paul, Romans 9:29 and which confirms the sense given of the above passages: "the very small remnant" are the remnant according to the election of grace, the little flock, the few that entered in at the strait gate and are saved, or the few that believed in Christ, and so were saved from that untoward generation; these were "left", reserved, distinguished, and secured in the grace of election, being a remnant according to it, in the hands of Christ to whom they were given, and in whom they were preserved; in redemption by him, that they might be a peculiar people; in providence till called, in which the Lord watched over them to do them good, and waited to be gracious to them, and saved them to be called; and in effectual calling, in which he separated them from the rest of the world, and kept them by his power through faith unto salvation. And this was done "unto us"; for the sake of his church, that that might continue, and he might have a seed to serve him: and by "the Lord of hosts", of the hosts of heaven, the sun, and moon, and stars, and of the angels there, and of the inhabitants of the earth; which shows great condescension in him to regard this remnant, and great grace to them; since he could not stand in need of them, having the host of heaven on his right hand and on his left; nor was there any thing in them that could deserve this of him; but it was, as Jarchi observes, in his mercy, and not for their righteousness: to which may be added, that since he is the Lord of hosts, he was able to protect and preserve this remnant, notwithstanding all the opposition of men and devils, as he did; and had he not taken such a method as this,
we should have been as Sodom, and we should have been like unto Gomorrah: cities that were infamous for their sins, and notorious for the punishment of them, being consumed by fire from heaven, Genesis 13:13 and not only the Jews, but any and every nation, even the whole world, would have been like these cities, both for sin and punishment, had it not been for the distinguishing grace of God, in leaving and reserving a few for his glory, and the support of his interest. All the holiness that ever was, is, or will be in the world, is owing to electing, redeeming, and efficacious grace: there had not been a holy man nor a holy woman in the world, in any age, if God had not taken such methods of grace; and it is owing to, and for the sake of, this small remnant, that temporal judgments are often averted from a nation and people, and that the conflagration of the world is not yet; this is kept back till they are gathered in; and were it not for this distinguishing grace, every individual of mankind would have been cast into hell, and must have suffered the vengeance of eternal fire, which the punishment of Sodom and Gomorrah, was an example of.

Jehovah of Sabaoth, that is, God of the angelic and starry hosts (Psalm 59:5; Psalm 147:4; Psalm 148:2). The latter were objects of idolatry, called hence Sabaism (2-Kings 17:16). God is above even them (1-Chronicles 16:26). "The groves" were symbols of these starry hosts; it was their worship of Sabaoth instead of the Lord of Sabaoth, which had caused the present desolation (2-Chronicles 24:18). It needed no less a power than His, to preserve even a "remnant." Condescending grace for the elect's sake, since He has no need of us, seeing that He has countless hosts to serve Him.

For the present, however, Jerusalem was saved from this extremity. The omnipotence of God had mercifully preserved it: "Unless Jehovah of hosts had left us a little of what had escaped, we had become like Sodom, we were like Gomorrah." Sarid (which is rendered inaccurately σπέρμα in the Sept.; cf., Romans 9:29) was used, even in the early Mosaic usage of the language, to signify that which escaped the general destruction (Deuteronomy 2:34, etc.); and כּמעט (which might very well be connected with the verbs which follow: "we were very nearly within a little like Sodom," etc.) is to be taken in connection with sarid, as the pausal form clearly shows: "a remnant which was but a mere trifle" (on this use of the word, see Isaiah 16:14; 2-Chronicles 12:7; Proverbs 10:20; Psalm 105:12). Jehovah Zebaoth stands first, for the sake of emphasis. It would have been all over with Israel long ago, if it had not been for the compassion of God (vid., Hosea 11:8). And because it was the omnipotence of God, which set the will of His compassion in motion, He is called Jehovah Zebaoth, Jehovah (the God) of the heavenly hosts - an expression in which Zebaoth is a dependent genitive, and not, as Luzzatto supposes, an independent name of God as the Absolute, embracing within itself all the powers of nature. The prophet says "us" and "we." He himself was an inhabitant of Jerusalem; and even if he had not been so, he was nevertheless an Israelite. He therefore associates himself with his people, like Jeremiah in Lamentations 3:22. He had had to experience the anger of God along with the rest; and so, on the other hand, he also celebrates the mighty compassion of God, which he had experienced in common with them. But for this compassion, the people of God would have become like Sodom, from which only four human beings escaped: it would have resembled Gomorrah, which was absolutely annihilated. (On the prefects in the protasis and apodosis, see Ges. 126, 5.)
