Isaiah 64 — «You Are Our Father, We the Clay»

This pericope belongs to the great communal penitential prayer that closes the book of Isaiah (chapters 63–64). In Hebrew numbering it runs from Isaiah 63:19b to 64:10, while in the Greek and Latin tradition it is counted as 64:1–11: this is why the verse numbers of the Hebrew apparatus and those of the common version never coincide by one unit. The voice is that of a community which, standing before the ruins of Jerusalem and the Temple, implores its God to tear open the heavens and come down as in the days of the theophany. The confession is radical: «we have all become like one who is unclean (tamèʾ), and all our righteousness like a filthy garment (bèged ʿiddìm)». This is a penitential hyperbole of post-exilic national guilt, not a doctrine about the intrinsic corruption of every good work: the language is that of ritual impurity in the cultic sense, not the anthropological-systematic register that centuries later would draw upon it.

Historical Reconstruction

The passage is situated in the final section of the book (chapters 56–66), traditionally assigned to a post-exilic milieu, after 538 BCE, when part of the exiles had returned to an impoverished Judah and a Jerusalem still bearing the marks of the Babylonian destruction of 587/586 BCE. Verses 9–11 (Hebrew numbering) presuppose a Temple already burned and a city reduced to desolation: «your holy cities have become a wilderness, Zion has become a wilderness, Jerusalem a desolation… the house of our holiness and glory… has become a prey to fire». The tone is not that of imminent catastrophe but of lamentation over a ruin already accomplished, which prompts the plea that the Tetragrammaton break his silence and intervene. The prayer interweaves the memory of ancient mighty acts — the descent upon the mountains, the dismay of the nations — with the bitter observation of a present in which «no one calls upon your Name». The one who prays claims no merit: he acknowledges the divine anger as the just consequence of the people's sin, and precisely for this reason invokes the only remaining title, the elective fatherhood of God.

Textual Notes (MT/LXX)

The divergences between the Masoretic Text (MT) and the Septuagint (LXX) are here particularly dense, a sign of a fluid textual tradition.

v. 1 (Heb.) — The MT opens with an image of burning, «as fire kindles brushwood (qedòach ʾesh), fire makes water boil», an allusion to the power that melts mountains. The LXX drastically simplifies to «as wax melts from fire», reducing the two parallel images to one. The stated purpose is «to make your Name (shem) known to your adversaries».

v. 2 (Heb.) — The «awesome deeds» (noraòt) of the MT become in the LXX «glorious things» (éndoxa): the fearsome aspect of the theophany is softened into a register of glory. The verb nazòllu («they melted, dissolved») is rendered by the LXX as «trembling seized the mountains», replacing the image of melting with that of trembling.

v. 3 (Heb.) — «Eye has not seen (ʿàyin loʾ raʾatàh) a God besides you». The LXX reads «nor have our eyes seen a God besides you», and adds that the divine works are «for those who await mercy (éleon)», making explicit the object that the MT leaves implicit in limchakkèh-lo, «for those who await him».

v. 4 (Heb.) — The MT joins joy and the practice of righteousness, «those who rejoice (sàs) and do what is right»; the LXX flattens this to «those who do what is right». The Hebrew conclusion is notoriously obscure («in them from of old — and shall we be saved?»); the LXX resolves it with «therefore we have gone astray», offering an interpretive reading.

v. 5 (Heb.) — The double simile remains in both witnesses: «like one who is unclean… like a filthy garment». The expression bèged ʿiddìm («menstruation cloth») is rendered by the LXX as rákos apokathēménēs, «a rag of a woman in seclusion», preserving the reference to female impurity. The term rùach at the end of the verse means «wind» here, even though it is the same word that elsewhere designates «spirit».

v. 6 (Heb.) — «No one calls upon your Name»: the absence of the cultic-invocatory act. The image of the «hidden face» (histàrta panèkha) is the typical sign of divine judgment and abandonment.

v. 7 (Heb.) — Here the proper Name of four letters appears for the first time in the passage, rendered as «the Tetragrammaton» in keeping with the traditional reading that avoids pronouncing it. The LXX translates it with kýrie, «Lord». This is followed by the vivid metaphors of clay (chòmer) and the potter (yotzrènu, «our fashioner»), which the LXX renders as «the work of your hands».

vv. 8–11 (Heb.) — The supplication «be not exceedingly angry… do not remember forever the iniquity (ʿawòn)» and the closing interrogative «in the face of all this will you restrain yourself (titʾappàq)?» are substantially in agreement in both witnesses, with the LXX turning the final question into a statement: «you have restrained yourself, you have kept silence and greatly humiliated us».

Jewish Reception (Liturgical and Rabbinic)

The image of the potter and the clay in Isaiah 64:7 (Heb.) has entered deeply into Jewish penitential liturgy. The celebrated piyyut Ki hinneh ka-chomer be-yad ha-yotzer («As clay in the hand of the potter»), recited in the evening liturgy of Yom Kippur, develops precisely this metaphor of creaturely dependence, elaborating it in a series of paired images (clay and potter, stone and chisel, iron and smith) to express the total submission of the one who prays to the divine hand. The verse thus became part of the heritage of the selichot, the prayers of supplication and pardon. More broadly, the entire chapter, with its choral confession «we have all become like one who is unclean», is read in the tradition as a model of communal teshuvah, in which sin is not claimed as fate but acknowledged as responsibility, from which one implores the return of the divine presence.

Aggadah

The midrashic tradition connects the potter metaphor of Isaiah 64:7 with the account of the creation of man from the dust (Genesis 2:7), reading in the term yotzèr («fashioner») the same root as the verb «wayyitzer» with which God «formed» Adam from the earth. In this aggadic reading, Isaiah's confession reminds the people of their creaturely origin: clay cannot contend with the potter, and the creature cannot reproach its Creator for the form received. It is plausibly within this framework that we should understand the recurrent connection in homiletical tradition between the humility of the penitent one who prays and the humility of Adam taken from the dust: humanity is called to recognise itself as chòmer, malleable matter, and to entrust itself to the mercy of the one who formed it. This connection is exegetical in nature and should be understood as interpretation, not as textual data of the Isaianic passage.

New Testament Reception and Typology

The best-known verse of the pericope in Christian reception is Isaiah 64:3 (Heb.) / 64:4 (common numbering): «from of old no one has heard… eye has not seen a God besides you». Paul takes it up freely in 1 Corinthians 2:9 («what eye has not seen, nor ear heard»), in a composite citation that blends the Isaianic text with other elements and refers it to the goods prepared by God for those who love him: this is a free use, not a precise rendering of the MT or of the LXX. The metaphor of the potter and the clay in Isaiah 64:7 also resonates in the argument of Romans 9:20–21, where Paul, taking up the prophetic motif (present also in Isaiah 29:16 and Jeremiah 18), asks whether the vessel can say to the potter «why have you made me like this?». Here too the apostle applies to his own argument a well-established Old Testament image, in a later, theologically reoriented reception distinct from the historical sense of the post-exilic communal prayer, which knows nothing of any problematic of individual election.

Observance and Liturgy

On the side of practice, the pericope nourishes penitential spirituality. In the Jewish tradition, as noted above, the motif of the clay and the potter structures the prayers of the penitential days, particularly in the cycle culminating in Yom Kippur. The collective confession — «we are all your people» (v. 8 Heb.) — grounds the liturgical use of communal lamentation, in which responsibility for sin is assumed by the entire assembly and not offloaded onto the individual: this is the model of vidduy, the plural confession recited in the plural («we have sinned»). The call to «make the Name known» among the nations (v. 1 Heb.) and the plea that the Tetragrammaton not keep silent «until the end» (v. 11 Heb.) frame the prayer as an active waiting for divine intervention, not as resignation: those who pray acknowledge the judgment, but lay claim to the faithfulness of the covenant God, who remains «our Father» (v. 7 Heb.) even when the sanctuary lies in ruins.

The Tannaitic Spine

A direct Tannaitic trace on this pericope is found in the Mekhilta de-Rabbi Yishmael, in the tractate Shirata on the Song of the Sea (Exodus 15). Commenting on the words «Who is like you among the gods, O Lord?» (Exodus 15:11), the sages illustrate the incomparability of God by citing precisely those prophetic passages that affirm divine uniqueness, in line with «eye has not seen a God besides you» in Isaiah 64. The same tradition, reflected also in tractate Sanhedrin of the Mishnah (chapter 10), which grounds the hope in the world to come on prophetic promises, shows how the expectation of what «eye has not seen» was already read in an eschatological key in the era of the Tannaim. Where precise Tannaitic documentation is uncertain, the most solid datum remains the liturgical use of the potter motif in the selichot, attested with certainty in the later tradition: it is therefore noted here soberly as liturgical reception, not as a securely ancient exegetical gloss.
