Isaiah 1:20

But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the LORD hath spoken it.

EXPOSITORY (ENGLISH BIBLE)

Matthew Henry's Concise Commentary

1:16-20 Not only feel sorrow for the sin committed, but break off the practice. We must be doing, not stand idle. We must be doing the good the Lord our God requires. It is plain that the sacrifices of the law could not atone, even for outward national crimes. But, blessed be God, there is a Fountain opened, in which sinners of every age and rank may be cleansed. Though our sins have been as scarlet and crimson, a deep dye, a double dye, first in the wool of original corruption, and afterwards in the many threads of actual transgression; though we have often dipped into sin, by many backslidings; yet pardoning mercy will take out the stain, Ps 51:7. They should have all the happiness and comfort they could desire. Life and death, good and evil, are set before us. O Lord, incline all of us to live to thy glory.

Barnes' Notes on the Bible

But if ye refuse, ye shall be devoured with the sword - Your enemies shall come in, and lay waste the land. This prediction was fulfilled, in consequence of their continuing to rebel, when the land was desolated by Nebuchadnezzar, and the nation was carried captive to Babylon. It illustrates a general principle of the divine government, that if people persevere in rebelling against God, they shall be destroyed. The word devour is applied to the sword, as if it were insatiable for destruction. Whatever destroys may be figuratively said to devour; see the notes at Isaiah 34:5-6; compare Isaiah 5:24; Lamentations 2:3; Ezekiel 15:4; Joel 2:3; Revelation 11:5 - where fire is said to devour.

The mouth of the Lord - Yahweh Himself. This had been spoken by the mouth of the Lord, and recorded, Leviticus 26:33 :

And I will scatter you among the heathen,

And will draw out a sword after you;

And your land shall be desolate

And your cities waste.

On these points God proposed to reason; or rather, perhaps, these principles are regarded as reasonable, or as commending themselves to men. They are the great principles of the divine administration, that if people obey God they shall prosper; if not, they shall be punished. They commend themselves to people as just and true; and they are seen and illustrated every where.

Jamieson-Fausset-Brown Bible Commentary

20. Lord hath spoken it—Isaiah's prophecies rest on the law (Le 26:33). God alters not His word (Numbers 23. 19).

Matthew Poole's Commentary

If ye refuse and rebel; if you obstinately persist in your disobedience to me, as hitherto you have done.

The mouth of the Lord hath spoken it; he hath said it, who can as easily do it as speak the words, and who cannot lie, and therefore will do it.

Gill's Exposition of the Entire Bible

But if ye refuse and rebel,.... The Targum is, "and do not receive my Word"; the Messiah, when come, neither his person, nor his doctrines and ordinances:

ye shall be devoured with the sword; of the Roman armies, as they were under Titus Vespasian; see Matthew 22:7.

for the mouth of the Lord hath spoken it; now, by Isaiah, as well as in former times, Leviticus 26:25.

Geneva Study Bible

But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the LORD hath spoken it.

EXEGETICAL (ORIGINAL LANGUAGES)

Cambridge Bible for Schools and Colleges

20. ye shall be devoured with the sword] “Sword” is here taken as an acc. of instrument, a construction of more than doubtful validity in Hebr. A more idiomatic rendering is: ye shall be made to eat the sword. An exactly similar expression is used by the Arabs, although Hebr. analogies are wanting.

21 ff. The elegy (qînâh, distinguished by a peculiar rhythm and by the opening word ’êkâh, “how”) is a frequent vehicle of prophetic utterance. This is the clearest instance in the genuine writings of Isaiah, and it is characteristic of the ‘city prophet’ (Cheyne), that the subject is not the nation but the idealised capital. Isaiah is in a good sense ‘laudator temporis acti.’ He laments the degeneracy of Jerusalem, looking back probably to the days of David, when it was the abode of judgment and righteousness.

Pulpit Commentary

Verse 20. - If ye refuse and rebel; i.e. "if ye neither consent in will, nor obey in act, "antithetical to the two verbs in the first clause of ver. 19. Ye shall be devoured; or, ye shall be eaten. The same verb as in the latter clause of ver. 19. With the sword. The metaphor is not a common one, but occurs in Jeremiah (Jeremiah 2:30; Jeremiah 12:12; Jeremiah 46:10, 14) and Nahum (Nahum 2:13). The mouth of the Lord hath spoken it. A weighty ending, indicating the certainty of fulfillment, Jehovah, who cannot lie, has spoken; the result will assuredly follow. Isaiah 1:20

Keil and Delitzsch Biblical Commentary on the Old Testament

But after the restoration of Israel in integrum by this act of grace, the rest would unquestionably depend upon the conduct of Israel itself. According to Israel's own decision would Jehovah determine Israel's future. "If ye then shall willingly hear, ye shall eat the good of the land; if ye shall obstinately rebel, ye shall be eaten by the sword: for the mouth of Jehovah hath spoken it." After their justification, both blessing and cursing lay once more before the justified, as they had both been long before proclaimed by the law (compare Isaiah 1:19 with Deuteronomy 28:3., Leviticus 26:3., and Isaiah 1:20 with the threat of vengeance with the sword in Leviticus 26:25). The promise of eating, i.e., of the full enjoyment of domestic blessings, and therefore of settled, peaceful rest at home, is placed in contrast with the curse of being eaten with the sword. Chereb (the sword) is the accusative of the instrument, as in Psalm 17:13-14; but this adverbial construction without either genitive, adjective, or suffix, as in Exodus 30:20, is very rarely met with (Ges. 138, Anm. 3); and in the passage before us it is a bold construction which the prophet allows himself, instead of saying, חרב תּאכלכם, for the sake of the paronomasia (Bttcher, Collectanea, p. 161). In the conditional clauses the two futures are followed by two preterites (compare Leviticus 26:21, which is more in conformity with our western mode of expression), inasmuch as obeying and rebelling are both of them consequences of an act of will: if ye shall be willing, and in consequence of this obey; if ye shall refuse, and rebel against Jehovah. They are therefore, strictly speaking, perfecta consecutiva. According to the ancient mode of writing, the passage Isaiah 1:18-20 formed a separate parashah by themselves, viz., a sethumah, or parashah indicated by spaces left within the line. The piskah after Isaiah 1:20 corresponds to a long pause in the mind of the speaker. - Will Israel tread the saving path of forgiveness thus opened before it, and go on to renewed obedience, and will it be possible for it to be brought back by this path? Individuals possibly may, but not the whole. The divine appeal therefore changes now into a mournful complaint. So peaceful a solution as this of the discord between Jehovah and His children was not to be hoped for. Jerusalem was far too depraved.
