Do Not Fear, I Have Redeemed You — Isa 43:1-28

Meaning. The chapter opens with a great word of consolation addressed to the Babylonian exile: the God who created and formed Israel (baracàkha…yotzercà, the two roots barà and yatzàr of the potter) is also his go'èl, the kinsman-redeemer who ransoms. The framework is that of the oracle of salvation, marked twice by the «do not fear» (al tirà, vv. 1.5), and that of the lawsuit (rìv): Israel becomes the legal witness to divine uniqueness before the nations and their idols. At the centre stands the monotheistic self-revelation «anì hu», «I am he» (vv. 10.13), and the announcement of the new Exodus — a way in the wilderness, rivers in the wasteland (v. 19) — which culminates in freely given forgiveness: «I, I am he who blots out your transgressions… for my own sake» (v. 25). The second half (vv. 22-28) reverses the tone: it is not the sacrificial cult that has wearied God, but the sins of the people, from the «first father» down to the princes of the sanctuary.

Historical Reconstruction

The passage belongs to the section commonly situated in the context of the Babylonian exile and the imminent liberation: the mention of Bavèl (Babylon) and the Chaldeans (v. 14) and the theme of the gathering of the dispersed from the east…from the west…from the north and from the south (vv. 5-6, the qibbùtz galuyòt) presuppose a deported community awaiting its return. The ransom «Egypt, Cush and Seba» (v. 3) plausibly evokes the geopolitical framework in which the rising Persian power was turning toward Africa: the God of Israel disposes of the nations as the price of exchange for his people. The theological horizon is that of polemical monotheism: against the gods of the conquering nations, the prophet proclaims that the only one who «announces and saves» is the Tetragrammaton, and that history itself — the ancient Exodus and the new one — is the judicial proof of his sovereignty. The structure of the chapter alternates two genres: the oracle of salvation (vv. 1-7, with the formulaic incipit «thus says…» and the double «do not fear») and the judicial dispute (rìv) against the nations and their idols (vv. 8-13), then returning to the promise of liberation (vv. 14-21) and closing with the indictment concerning cult and sin (vv. 22-28). The images of passing through «the waters» and «the fire» (v. 2) do not describe generic trials but plausibly evoke the founding memory of the Sea and the concrete threats of exile, reread as scenarios in which the divine presence («I am with you») guarantees the safety of the redeemed people.

Textual Notes (MT/LXX)

The Masoretic text and the Septuagint diverge at several significant points. At v. 2 the Hebrew has the plural «the waters» (bammàyim) while the LXX uses the singular δι' ὕδατος. At v. 3 the place names Kush and Sevà become in the LXX «Ethiopia and Syene» (Αἰθιοπίαν καὶ Σοήνην). At v. 4 the Hebrew adàm tachtècha we-le'ummìm («men in your place and peoples») is amplified by the LXX as ἀνθρώπους πολλούς and ἄρχοντας, «many men…princes». Verse 14 is notoriously obscure: the MT alludes to fugitives and to «the Chaldeans in the ships of their jubilant cry», while the LXX reads ἐπεγερῶ…φεύγοντας and «the Chaldeans will be bound on ships». At v. 20 the Hebrew tannìm (jackals) is rendered by the LXX as σειρῆνες, «sirens». At v. 21 tehillatì («my praise») becomes τὰς ἀρετάς μου, «my virtues/excellences». At v. 22 a reversal of sense is found: the MT has «you have wearied of me» (ki yagà'ta bi), while the LXX negates «nor have I made you labour» (οὐδὲ κοπιᾶσαί σε ἐποίησα). Characteristic is the emphatic pronominal reduplication anokhì anokhì at vv. 11.25, faithfully rendered by the LXX as ἐγώ εἰμι ἐγώ εἰμι (v. 25), which ancient Christian reading will interpret as a formula of divine identity. It should furthermore be noted that the short formula anì hu of vv. 10.13 («I am he») is translated by the LXX with the simple ἐγώ εἰμι, flattening the specifically Hebrew use of the third-person pronoun hu in a quasi-nominal predicative function: it is precisely this shift that made the Greek version so malleable for Johannine Christology. At v. 7 the Hebrew accumulates three creation verbs in climax — «bera'tìw yetzartìw af 'asitìw» (I created him, I formed him, and indeed I made him) — resuming the two roots of the incipit; the LXX preserves them as κατεσκεύασα…ἔπλασα…ἐποίησα. At v. 17 the image of the wick that is quenched (kappishtà kavù) is rendered with the participle ἐσβεσμένον, underscoring the irreversibility of the pursuers' extinction. The khofer of v. 3 («ransom») belongs to the semantic field of atonement-covering (root kpr), but the LXX neutralises it as ἄλλαγμα, a simple «exchange», losing the cultic echo.

Jewish Reception (Rabbinic and Liturgical)

The declaration «attèm edài», «you are my witnesses» (vv. 10.12), is among the most commented in the tradition: rabbinic reading finds in it a reciprocal and almost vertiginous bond between Israel and God. The Tannaitic source Sifre Devarim 346 (section Ha'azinu), commenting on Deuteronomy 32:3, explicitly cites «ואתם עדי…ואני אל» of Isaiah 43:12 and derives from it the bold formula: when Israel bears witness, the Name is acknowledged as God; otherwise, so to speak, his sovereignty remains unconfessed in the world. Human testimony adds nothing to the divine being, but is the historical condition of his manifestation among the nations. The root of redemption (g'l, the go'èl) also belongs to the halakhic lexicon of the blood-avenger and the redemption of family property (cf. Leviticus 25), and here it is transferred to the covenantal relationship: God acts toward Israel as the nearest kinsman obliged to redeem. The promise «when you pass through the waters…they shall not overwhelm you…the fire shall not burn you» (v. 2) has also entered the consolatory repertoire of the tradition as a word of protection in times of persecution, frequently placed alongside the memory of the Sea and the episode of the three young men in the furnace (cf. Daniel 3). The statement «I have called you by your name, you are mine» (v. 1) is read as a sign of personal and not merely collective election, while those «called by my name…created for my glory» of v. 7 ground the dignity of Israel as a people formed for the purpose of praise (v. 21, tehillatì yesappèru).

Aggadah

The aggadic motif most frequently grafted onto this chapter concerns the self-revelation «anì hu» (vv. 10.13). The narrative tradition connects it to the declarations at the Red Sea and the liturgical recitation of the Hallèl: the God who «opens a way in the sea» (v. 16) and overwhelms «chariot and horse» (v. 17) is the same who now accomplishes a «new» wonder. The aggadah also amplifies v. 25, «anokhì anokhì hu mochè», as proof of the gratuity of forgiveness: God blots out transgressions «for my own sake» (lema'anì), not on account of the people's cultic merits — a reading that aligns with the description of the «useless» sacrifices of vv. 22-24. As for the «first father» (avìkha harishòn) of v. 27, exegetical tradition oscillates, identifying him variously with Adam, with Abraham, or, most frequently, with Jacob-Israel himself, the eponymous ancestor of the people: this remains an interpretive proposal and not a univocal assertion.

New Testament Reception and Typology

The chapter has left deep traces in the New Testament. The absolute formula «anì hu» / ἐγώ εἰμι (vv. 10-13) constitutes plausibly the Old Testament background of the «I am» declarations of the Gospel of John, in particular John 8,24 («if you do not believe that I am, you will die in your sins»), John 8,58 and John 13,19 (the latter takes up almost verbatim «so that you may believe that I am», an echo of Is 43,10). The self-predication «I am the first and the last» from the same Deutero-Isaianic strand (cf. Is 44,6; 48,12) resurfaces in Revelation 1,17. The theme of «doing new things» (v. 19, chadashà / καινά) resonates in the theology of new creation in 2 Corinthians 5,17 and in the «I make all things new» of Revelation 21,5. The mandate to be «witnesses» (vv. 10.12) is typologically reread in the apostolic mission of Acts 1,8 («you will be my witnesses…to the ends of the earth»), which takes up the language of the gathering from the ends of the earth of v. 6. These are in every case resonances and echoes, in keeping with the New Testament practice of rereading the prophet of the exile, not explicit formal citations in every instance.

Observance and Liturgy

For the synagogal tradition, passages from this section of the book form part of the cycle of haftaròt of consolation read in the weeks following the fast of the Ninth of Av (the seven haftaròt deNechamtà), in which Israel hears anew the promise of return and redemption. The key verse «you are my witnesses» (v. 10) has had a particular devotional resonance as the foundation of the people's testimonial vocation. At the level of daily prayer, the exclusive monotheistic affirmation of vv. 10-11 («before me no god was formed…besides me there is no saviour») stands in full consonance with the profession of uniqueness in the Shemà and with its liturgical confession of the one saving God. The theme of gratuitous forgiveness of v. 25 («he who blots out your transgressions…I will remember your sins no more») finally nourishes the penitential language of the Days of Awe, in which the blotting out of guilt is invoked not by merit but by pure mercy.
