For I am the Lord thy God, the Holy One of Israel, thy Saviour: I have given Egypt for thy atonement, Ethiopia and Saba for thee.

“And now thus says the Lord, etc. Here he shows them the divine love through the remedies which he granted them amid their distresses. And it is divided into three parts. In the first he promises future remedies, to show his love; in the second he recalls past benefits, to confirm the promise: "thus says the Lord, who gave," etc.; in the third he excludes merits, to take away presumption: "you did not call upon me," etc. Concerning the first he does three things. First he shows toward them the privilege of divine love; second, from the promised remedies, he excludes any partnership in divine power: "all the nations are gathered together," etc.; in the third he sets forth the sign of his love: "thus says the Lord your redeemer," etc. Concerning the first, he promises them three remedies. First, sustenance in punishments, excluding fear by the divine presence: "creating you" — as to the principles of substance, Deut. 32: "he is your father," etc.; "forming" — as to the form which he gave, Gen. 1: "the Lord formed," etc.; "redeeming" — from evils, Hosea 13: "from the hand of death," etc.; and "I have called" — unto grace, Hosea 1: "I will call 'not my people,'" etc. He sets forth the promise: "when you shall pass through the waters" — the Egyptians; "the rivers" — the Chaldeans; "the fire" — the Greeks; "the flame" — the Romans. For they were not consumed entirely. Ps. 65: "we passed through fire," etc. And he assigns the reason for this: "for I am the Lord," etc., above, 12: "for he himself, God, is savior," etc. Second, he promises a commutation of punishments, namely that he will punish others in his place. And he sets forth the commutation. "I have given a propitiation" — that is, that I might be propitiated toward you, as it were by the punishments of those who provoked you to sin by the hope of their help. "Saba" — a city of Ethiopia. Prov. 11: "the just man out of distress," etc. And he assigns the reason, namely God's own love: "since you have become honorable" — that is, I have made and accounted you honorable. "For you" — for your liberation. Jer. 31: "if a son honorable to me," etc. Third, he promises them liberation of every kind from tribulations; and concerning this, three things. First he promises the benefit of liberation: "do not fear, from the east" — because they had been scattered in every direction. Above, 11: "he will gather the fugitives," etc.; Jer. 31: "behold I will bring them," etc. Second, he sets forth the merit of liberation: "and everyone who calls upon me I will bring" — "unto my glory," that he may glorify me, and I may appear glorious in him. Joel 2: "everyone whosoever shall call upon," etc. Third, he promulgates the precept of liberation. "Bring forth," O Cyrus, "outside" — outside the land of captivity — "the people," namely of the Jews. Jer. 5: "hear, foolish people," etc. "All the nations." Here he excludes any partnership in godhead. And first he shows the falsity of the other gods by way of a judgment, setting forth the nations' agreement with idols: "are gathered together" — into one error. Ps. 13: "all have gone astray," etc. — seeking a sign of godhead. "Who among you" — that is, which of your gods? Or he speaks to the idols, and seeks testimony. "Let them give witnesses," and "let them be justified" — that is, let them be justly called gods; and let the witnesses hear future things from them, and speak testimony on your behalf. Above, 41: "there is none announcing nor foretelling," etc. Second, he shows the truth of his own godhead: and first as to knowledge; second as to power, "you are witnesses," etc. Concerning the first, two things. First he gives testimony, assigning men as witnesses: "truly you are witnesses," etc.; "my servant" — the people of Jacob, or Christ. Acts 1: "you shall be witnesses to me," etc.; setting forth the manner of knowing: "that you may know" — as to those things which can be known of God through natural reason; and "that you may believe" — as to those things which are above reason; and thus "you may understand": for unless you shall have believed, you shall not understand, above, 8, according to another text. He also sets forth the saying of the witnesses, that he alone is God: "for I alone" — "I am" — "God." "The one who forms," or "the one formed" — namely, an idol — Deut. 32: "see that I am he alone," etc.; and that he alone is Lord: "I am" — singularly; "I am" — excellently, etc.; Acts 4: "there is no salvation in any other," etc. Second he gives a sign of godhead. "I have announced," etc.; "there was not" one from whom you could know. Ps. 80: "Israel, if you will hear me," etc. "You are witnesses," etc. Here he shows the truth of his godhead as to power: and first he gives testimony, "you are witnesses," etc., John 8: "I am the beginning," etc. Second he gives a sign of power in punishing: "and there is none who" out of the "hand" — as Deut. 32, Job 10; and in working, "I will work," etc., above, 14: "the Lord of hosts has decreed," etc. "Thus says the Lord," etc. Here he sets forth the sign of love: because for their sake he destroyed the Babylonians glorying in their ships, on account of the multitude of waters. "I have sent forth" — namely, wrath — Jer. 51: "the Lord has planned and has done," etc. "Thus says the Lord who gave," etc. Here he recalls past benefits, to confirm hope concerning future ones. And concerning this he does two things. First he recalls the past benefits when they went out from Egypt, in their governance. "In the sea" — the Red Sea, Exod. 14; "in the waters of the torrent" — in the Arnon, Numbers 21; in the Jordan, Joshua 3. And as to the destruction of enemies: "who brought forth the chariot" — the chariots of Pharaoh, etc., Exod. 15: "his chosen princes," etc.; "as flax" — cut off in a moment. Second he promises things much greater in the future; and concerning this he does three things. First he shows the greatness of future benefits by comparison with the former: "do not remember" — as if to say: they are not worthy to be held in memory in comparison with the future ones, Phil. 3: "forgetting indeed those things which are behind," etc.; by their newness: "behold I make new things" — unheard of, Apoc. 21: "behold I make all things new." And by their determination: "I will set in the desert" — that is, in the land of the Jews, which was formerly desert — "a way" — of those going to the festivities; "rivers" — of consolation, Ps. 106: "he turned the desert into pools," etc. And if these things are expounded literally of the liberation from the captivity of Babylon, they are said to be greater than the liberation from Egypt — not on account of greater miracles, but because the kings from whose power he liberated them were more powerful than Pharaoh; or because they came from a more distant place. But if they are referred to the liberation wrought through Christ, it is clear that nothing so admirable had preceded it in past ages. Second he shows the usefulness of the benefits among the nations: "and the beast of the field will glorify" — that is, the Gentile living beastially, converted to Christ; or those seeing how I free the Jews. Ps. 148: "beasts and all cattle," etc.; and among the Jews: "that I might give drink" — of doctrine and consolation, Deut. 7: "the Lord has chosen you," etc. Third he assigns the reason: "this people for myself" — unto my praise. Prov. 16: "all things for himself," etc. "You did not call upon me." Here he excludes the merits of the Jews for obtaining such great benefits; and concerning this, three things. First he excludes merit; second he gives room for a response, "bring me back to mind," etc.; third he removes a certain manner of responding, "your father," etc. Concerning the first, three things. First he excludes merit: "you did not call upon me" — and all these things are said because they did not offer these things to God with their whole heart, but partly to God, partly to idols; or because they conferred nothing on God; or because they did them in hope of temporal recompense; or because after the coming of Christ they were not accepted. Mal. 3: "who is there among you that would shut the doors," etc.; Ps. 49: "shall I eat," etc. Second he shows their guilt: "nevertheless, to serve" — as if to say: you have shown me servile, while, though you offended me, I did not punish. Above, 1: "they have become troublesome to me," etc. He speaks in a human manner. Third he shows the benefit given freely: "I am," etc., Ps. 24: "for your name's sake you will be propitious," etc., Ez. 36: "not for your sakes will I do this," etc. "Bring me to remembrance," etc. Here he gives room for a response. "Bring back" — as if to say: think again on what I have done for you; tell if you have anything, to excuse yourself, or to accuse me, that you may be justified, that is, that you may be judged just. Job 33: "if you have anything to say," etc. "Your father." Here he removes a certain way of responding. For they could allege the innocence of their fathers; but against this he speaks. "Father" — Adam, Gen. 3; Abraham, seeking a sign concerning God's promise, as though doubting, Gen. 15; "interpreters" — Moses and Aaron at the waters of contradiction, Num. 21; "I have profaned" — that is, I have allowed to be profaned — unto utter destruction: for all died in the desert, except Caleb and Joshua. Ps. 105: "we have sinned with our fathers," etc. (Collationes, chap. 43). The Lord frees the saints from fire: of carnal temptation, Job 31: "it is a fire even unto consumption," etc.; of temporal tribulation, Ps.: "you have tried me by fire"; of eternal damnation, Matt. 25: "depart, you cursed"; of divine indignation, Deut. 32: "a fire is kindled," etc. In which are burned: the lascivious, 1 Cor. 7: "it is better to marry," etc.; the impatient, above, 13: "their faces shall be burnt," etc.; the impenitent, Ps.: "the flame has burned up sinners"; the proud, the same: "the foundations of the mountains," etc. He also frees from waters: of pleasure, Prov. 9: "stolen waters," etc., in which they are suffocated through luxury; of cupidity, Exod. 15: "they sank as lead," etc., in which through avarice; of adversity, Ps.: "the waters have come in even unto the soul," etc., in which through impatience; of worldly power, Apoc. 17: "the waters upon which she sits," etc., in which through pride. Bring God back into memory as to: the wonders which he has done, that they be venerated, Ps.: "remember his wonders," etc.; the benefits which he gave, that thanks be rendered, Ecclus., last chapter: "I have remembered mercy," etc.; the torments which he endured, that compassion be shown, Lam. 3: "remember my poverty," etc.; the precepts which he gave, that they be observed, Ps.: "that they may be mindful," etc.”

“For I am the Lord thy God, the Holy One of Israel, thy Saviour,.... The Lord is the covenant God of his people, holy in himself, and the sanctifier of them, and their Saviour in time of trouble; and therefore need no doubt of his presence and support amidst all their afflictions; and besides they should call to mind past experiences of his goodness, to encourage their faith in him, as to present help and assistance: I gave Egypt for thy ransom; he sacrificed the Egyptians instead of the Israelites; he destroyed the firstborn of Egypt, and saved Israel his firstborn; he drowned the Egyptians in the Red sea, when the Israelites passed safely through it; and the destruction of the former was to make way for the salvation of the latter, and so said to be a ransom for them; see Pro 11:8, Ethiopia and Seba for thee; this refers either to the rumour brought to Sennacherib of Tirhakah king of Ethiopia coming against him to war, which diverted him from the siege of Jerusalem for a time, and caused him to turn his forces upon the Ethiopians and Sabeans, whereby the Jews had a respite, Kg2 19:9 or rather to the overthrow of the Ethiopians in the time of Asa, Ch2 14:9 or to the king of Assyria, perhaps Shalmaneser's being diverted from Palestine and Judea, and turning his forces upon Egypt and Ethiopia, as in Isa 20:1 and the Lord, by putting his people in mind of these instances, suggests hereby that he will sacrifice all their enemies, rather than they shall be destroyed, and therefore they need not fear.”

“Egypt for thy ransom--Either Egypt or Israel must perish; God chose that Egypt, though so much more mighty, should be destroyed, in order that His people might be delivered; thus Egypt stood, instead of Israel, as a kind of "ransom." The Hebrew, kopher, means properly "that with which anything is overlaid," as the pitch with which the ark was overlaid; hence that which covers over sins, an atonement. Nebuchadnezzar had subdued Egypt, Ethiopia (Hebrew, Cush), and Saba (descended from Cush, Gen 10:7, probably Meroe of Ethiopia, a great island formed by the Astaboras and the Nile, conquered by Cambyses, successor of Cyrus). Cyrus received these from God with the rest of the Babylonian dominions, in consideration of his being about to deliver Israel. However, the reference may be to the three years' war in which Sargon overcame these countries, and so had his attention diverted from Israel (see on Isa 20:1) [VITRINGA]. But the reference is probably more general, namely, to all the instances in which Jehovah sacrificed mighty heathen nations, when the safety of Israel required it.”

“Just as in Isa 43:1, kı̄ (for), with all that follows, assigns the reason for the encouraging "Fear not;" so here a second kı̄ introduces the reason for the promise which ensures them against the dangers arising from either water or fire. "For I Jehovah am thy God; (I) the Holy One of Israel, thy Saviour: I give up Egypt as a ransom for thee, Ethiopia and Seba in thy stead. Because thou art dear in my eyes, highly esteemed, and I loved thee; I give up men in thy stead, and peoples for thy life." Both "Jehovah" and "the Holy One of Israel" are in apposition to "I" ('ănı̄), the force of which is continued in the second clause. The preterite nâthattı̄ (I have given), as the words "I will give" in Isa 43:4 clearly show, states a fact which as yet is only completed so far as the purpose is concerned. "A ransom:" kōpher (λύτρον) is literally the covering - the person making the payment. סבא is the land of Mero, which is enclosed between the White and Blue Nile, the present Dr Sennr, district of Sennr (Sen-rti, i.e., island of Sen), or the ancient Meriotic priestly state settled about this enclosed land, probably included in the Mudrya (Egypt) of the Achaemenidian arrowheaded inscriptions; though it is uncertain whether the Kusiya (Heb. Kūshı̄m) mentioned there are the predatory tribe of archers called Κοσσαῖοι (Strabo, xi. 13, 6), whose name has been preserved in the present Chuzistan, the eastern Ethiopians of the Greeks (as Lassen and Rawlinson suppose), or the African Ethiopians of the Bible, as Oppert imagines. The fact that Egypt was only conquered by Cambyses, and not by Cyrus, who merely planned it (Herod. i. 153), and to whom it is only attributed by a legend (Xen. Cyr. viii. 6, 20, λἐγεται καταστρἐψσασθαι Αἰγυπτον), does no violence to the truth of the promise. It is quite enough that Egypt and the neighbouring kingdoms were subjugated by the new imperial power of Persia, and that through that empire the Jewish people recovered their long-lost liberty. The free love of God was the reason for His treating Israel according to the principle laid down in Pro 11:8; Pro 21:18. מאשׁר does not signify ex quo tempore here, but is equivalent to אשׁר מפּני in Exo 19:18; Jer 44:23; for if it indicated the terminus a quo, it would be followed by a more distinct statement of the fact of their election. The personal pronoun "and I" (va'ănı̄) is introduced in consequence of the change of persons. In the place of ונתתּי (perf. cons.), ואתּן commended itself, as the former had already been used in a somewhat different function. All that composed the chosen nation are here designated as "man" (âdâm), because there was nothing in them but what was derived from Adam. תּחת has here a strictly substitutionary meaning throughout.”
