Isaiah 66:11 Commentary: Nursing at the Breasts of Consolation

Isaiah 66 is the final chapter of the book, a dramatic conclusion that sets judgment against restoration. The preceding verses (7, 9) describe a sudden and miraculous birth: Zion travails and brings forth a nation in a single day. This birth is God’s doing, not human effort. Verse 10 then calls the faithful to rejoice, and verse 11 gives the reason: they will nurse from Jerusalem’s abundance.

The image of Jerusalem as a mother was well established in Israel’s poetry. In the ancient Near East, cities were often personified as women, and their fate was described in maternal terms, either fruitful and nurturing, or barren and desolate. Here the restored Jerusalem becomes a nursing mother, and her children are the faithful who have loved her and mourned over her (Isa 66:10). The “breasts of consolations” echo the earlier promise in Isaiah 40:1: “Comfort, comfort my people.”

The context makes clear that this comfort is not for everyone. It is for those who “tremble at his word” (66:5), who have been persecuted and cast out. The nursing metaphor assures them that their grief will be turned into satisfaction. In the post-exilic setting, when the city lay in ruins and the people were scattered, this word would have been explosive hope: Jerusalem would again become a source of life, so abundant that the nations would stream to her (66:12). The call to “drink deeply” and “delight” (anag) suggests not mere necessity but pleasure, even playfulness. God’s comfort is not a grudging ration; it is a lavish feast. The verse reorients the faithful from mourning to joyful anticipation, grounding that joy in the concrete reality of God’s restorative work.

The supplied commentaries note a textual difficulty with the word ziz (rendered “abundance” in most English versions). Adam Clarke cites manuscript variations: two manuscripts and an early edition read mizziv (“from its splendor”) instead of mizziz. The rabbis Kimchi and Sal. ben Melec effectively acknowledged an error by claiming the word means the same as the variant. Clarke proposes reading mizzen (“from stores”). The Cambridge Bible for Schools and Colleges observes that ziz appears elsewhere only in Psalm 50:11 and 80:13, where it means “beast” (as in “beast of the field”), making the meaning here uncertain. Ewald and Cheyne suggest the word may be cognate to an Assyrian or Arabic term for “udder,” which would fit the nursing metaphor perfectly. The Septuagint translates differently, and the Vulgate and Targum also show variation. None of the textual options change the overall sense of abundant consolation; the metaphor of nursing remains clear regardless of the exact noun used.

From the early church onward, this verse has been treasured as a promise of God’s intimate comfort. Patristic writers used the nursing imagery to speak of the church as a mother who nourishes believers with the milk of sound doctrine and the sacraments. In the medieval period, the verse was applied to the beatific vision: the soul’s ultimate satisfaction in God’s glory. Reformers like Calvin and Luther read it as the consolation believers receive through the preached word and the Lord’s Supper. The Jewish tradition, represented by Kimchi and other rabbis, wrestled with the textual difficulty of ziz but consistently saw the verse as a picture of the joy to come when Jerusalem is restored. In modern devotional writing, the image continues to comfort those who grieve, reminding them that God’s comfort is as close and nourishing as a mother’s milk.

Three-point outline

1. Rejoice with Jerusalem (v.10). The command to joy is rooted in the community: those who love the city and mourn over her are called to join her celebration. Comfort is not individualistic; it is shared in the body of the faithful.
2. Nurse from her abundance (v.11). The means of comfort is pictured as breastfeeding, intimate, nourishing, wholly satisfying. The church’s consolations (Scripture, sacraments, fellowship) are the milk that sustains God’s people.
3. Be comforted by God (v.13). The ultimate source is the Lord himself, who comforts “as one whom his mother comforts.” The metaphor circles back to divine tenderness.

Five-point outline

1. The call to shared joy (v.10)
2. The promise of satisfaction (v.11a: “suck and be satisfied”)
3. The depth of delight (v.11b: “drink deeply and delight”)
4. The flood of peace and glory (v.12: river and stream)
5. The mother-heart of God (v.13)

Illustration hooks

• A nursing infant. A baby does not earn milk or measure it. He simply receives, trusting that the mother will provide. This pictures the posture of faith: open, dependent, expectant.
• A long drought broken by rainfall. When the ground has been dry for months, the first soaking rain is not just water, it is relief. The promise of “abundance of her glory” speaks to a spiritual drought that will be ended.
• A community meal after a funeral. Grieving families often gather to share food. The meal does not remove the loss, but it binds the mourners together and offers tangible care. The call to “rejoice with Jerusalem” acts like that meal: it transforms isolation into shared hope.

Questions your congregation is asking

• Why does God use such a physical, even maternal image for comfort? It teaches that divine consolation is not abstract; it touches our bodies, our hunger, our deepest need for intimacy.
• What do I do if I don’t feel comforted? The verse is a promise, not a command to manufacture feelings. It invites us to place ourselves in the community of faith, to keep coming to the “breasts of consolation,” even when satisfaction is not immediate.
• How does this apply to our church today? If the church is the Jerusalem that nourishes, then our fellowship, teaching, and sacraments are the means by which God’s comfort flows. We are both recipients and, in a sense, the mother’s body through which others are fed.

This verse uses an image that can be startling in its intimacy: nursing from a mother’s breast. The metaphor is meant to communicate that God’s comfort is as close and as necessary as a mother’s milk to a hungry child. As you talk through this passage, pay attention to the physicality of the language, the sucking, the satisfaction, the delight. God is promising something that reaches the whole person.

Discussion questions

1. Read Isaiah 66:10, 11 together. What emotions do the images of nursing and milk evoke for you? How do they shape your understanding of God’s comfort?
2. Verse 10 calls us to rejoice “with Jerusalem.” Why is it important that comfort is experienced together, not alone? Can you think of a time when shared grief turned into shared hope?
3. The Hebrew word maatsats (v.11, “drink deeply” or “milk out”) suggests draining the breast completely. What does it mean to be fully satisfied by God’s consolation? What gets in the way of that satisfaction in your life?
4. Verse 13 says, “As one whom his mother comforts, so I will comfort you.” How is God’s comfort like a mother’s? How is it different? Does this image expand or challenge your picture of God?
5. In the context of Isaiah 66, comfort comes to those who “tremble at his word” (v.5) and mourn over Jerusalem. Why is suffering or grief connected to receiving comfort? How does that connect to the Beatitudes (Matthew 5:4, “Blessed are those who mourn”)
6. The last part of verse 11 mentions “the abundance of her glory” (literally “from the nipple of its glory”). Some translations use “brightness” or “splendor.” How does God’s glory become a source of nourishment and delight?
7. How can this passage shape the way our small group or church offers comfort to those who are hurting? What practical steps could we take to be “breasts of consolation” for one another?
