Psalms 137.9

Book: Psalms · NASB95

Verse

"How blessed will be the one who seizes and dashes your little ones against the rock." (Psalms 137:9, NASB95)

Immediate context (the entire psalm)

"By the rivers of Babylon, there we sat down and wept, when we remembered Zion. Upon the willows in the midst of it we hung our harps. For there our captors demanded of us songs, and our tormentors mirth, saying, 'Sing us one of the songs of Zion.' How can we sing the LORD'S song in a foreign land? If I forget you, O Jerusalem, may my right hand forget her skill. May my tongue cling to the roof of my mouth if I do not remember you, if I do not exalt Jerusalem above my chief joy. Remember, O LORD, against the sons of Edom the day of Jerusalem, who said, 'Raze it, raze it to its very foundation.' O daughter of Babylon, you devastated one, how blessed will be the one who repays you with the recompense with which you have repaid us. How blessed will be the one who seizes and dashes your little ones against the rock." (Psalms 137:1-9, NASB95)

Setting

Speaker: an unnamed Israelite poet, likely a Levitical / temple musician (cf. v. 2's "harps") writing during or shortly after the Babylonian exile.
Audience: the Jewish exilic / post-exilic community, the song was composed to be sung in worship as lament-and-imprecation.
Location: al-naharot Bavel, "by the rivers of Babylon", the canal-and-river network of Mesopotamian Babylonia (Tigris, Euphrates, and their associated canals where Jewish exiles were settled, per Ezekiel 1:1, 3:15).
Time period: composition c. 586-538 BC (during the Babylonian exile) or shortly after the return (c. 538-520 BC), when the trauma was still raw. The reference to Babylon as "you devastated one" (v. 8), using a future-anticipatory or possibly past-tense voice, fits the post-538-BC fall-of-Babylon period.

Theological reading, the imprecatory psalms

The psalm is the most notorious imprecatory psalm in the Psalter, and v. 9 is the most-cited single verse for the apologetic challenge "the Bible commands killing babies." Three distinct exegetical claims:

1. Genre, imprecatory lament psalm

Psalm 137 belongs to the imprecatory psalm genre (cf. Psalms 35, 55, 58, 59, 69, 79, 109, 137, 139). Imprecatory psalms include curses, cries for vengeance, and (in this case) a beatitude pronounced over violent retribution. The genre's characteristics:

Address to God in the second person (sometimes shifting to imperative-cursing of enemies)
Honest expression of grief, anger, and longing for justice
Appeal to God to act as judge / avenger
Articulation of the lex talionis principle ("you will be repaid as you repaid us")
Trust in God to execute the judgment (not the speaker / community taking violent action themselves)

The psalmist is not commanding violent action; he is expressing trust that the just God will deal with Babylon as Babylon dealt with Israel.

2. Historical context, what Babylon did to Israel's babies

The psalm's beatitude is contextually tied to specific historical atrocities. When Babylon sacked Jerusalem in 586 BC (and previously in 597, 605):

Babylonian forces burned the temple, leveled the city walls, slaughtered residents
2 Kings 25:7, King Zedekiah was forced to watch his sons killed before his eyes were put out
Lamentations 2:11-12, 19-20, graphic descriptions of starving infants dying in the streets, mothers cooking and eating their own children during the siege
Lamentations 4:10, "the hands of compassionate women boiled their own children; they became food for them because of the destruction of the daughter of my people"
Lamentations 5:11-13, mass rape, mutilation, enslavement

In ancient Near Eastern warfare, the killing of infants was a documented Babylonian / Assyrian / Persian standard practice, Hosea 13:16; Nahum 3:10, to prevent future generations of resistance. The psalm's v. 9 is a cry that Babylon receive the same atrocity it inflicted, an articulation of the lex talionis (eye-for-eye) principle, addressed to God as the just judge.

3. The beatitude form, "blessed (ashrei) is the one who…"

The Hebrew ashrei (blessed / fortunate / happy) is the same term that opens Psalm 1:1 ("Blessed is the man…"). The form: the one who serves God's just retribution against Babylon will be considered blessed / approved, because they execute divine justice. This is not a command for individuals to seek out and kill Babylonian infants; it is a poetic-theological articulation that Babylon's deserved judgment, when it comes, will be just, and those who execute it serve a just cause.

Three approaches to the imprecatory psalms

The history of Christian engagement with imprecatory psalms (esp. Psalm 137:9) yields three main approaches:

1. The "honest lament" approach (modern conservative consensus). The imprecatory psalms are honest expressions of human anguish, not models of Christian prayer per se, but inspired preservations of how God's people actually feel when subjected to atrocity. The psalmist:

Does not take violent action himself
Hands the matter over to God as judge
Articulates the lex talionis expectation honestly
Is not endorsed-as-prescription; the verse is describing, not prescribing

This approach acknowledges the verse's harshness without endorsing infanticide, recognizing the genre as lament-cry-for-justice.

2. The "Christological / typological" approach (patristic and medieval). The "babies of Babylon" represent spiritual evil, the early-formed "infant" sins of the soul that, if allowed to mature, become full-grown habits of vice. Augustine (Sermons on the Psalms 137; Confessions I.6-7), Origen, and the patristic tradition generally read this allegorically: the Christian's calling is to dash the infant temptations against the Rock (Christ, 1 Corinthians 10:4). On this reading, v. 9 becomes a poem about mortifying nascent sin in oneself. The reading has theological merit (mortification of sin is a real biblical theme, Romans 8:13; Colossians 3:5) but it should not be a substitute for honest engagement with the literal-historical reading.

3. The "Christ-fulfilled / canonical-progression" approach (modern Reformed and conservative-evangelical). The imprecatory psalms reflect a stage of progressive revelation in which Israel cried out for divine justice within an Old-Covenant framework. The NT fulfills and transforms this:

Christ commands love of enemies (Matthew 5:44)
Christ Himself prays for His enemies' forgiveness on the cross (Luke 23:34)
The final judgment is reserved for God (Romans 12:19; Revelation 18-19)
The imprecatory longing is redirected, Christians long for God's vindication of justice through the gospel + final judgment, not through personal vengeance

This approach affirms the psalms' validity within their canonical-historical context while reading them in light of Christ's fulfillment.

The apologetic challenge, "the Bible commands killing babies"

The verse is widely cited by atheist / skeptical apologists (especially the New Atheists, Dawkins, Hitchens) as evidence that the Bible commands genocide / infanticide. ris3n's note cluster ("Babies killed in Bible"; "Dashing Babies oh noo") engages this directly. The defense:

The verse is not a divine command. It is a human cry of grief by a survivor of atrocity, addressed to God. The psalm is the prayer of an exile, not God's instruction to Israel. Failing to distinguish descriptive from prescriptive readings collapses the genre.
The verse expresses lex talionis against a documented atrocity-perpetrator. Babylon killed Israel's infants; the psalmist cries out for proportional justice. To call this "advocating infanticide" is to ignore (a) the historical context of what Babylon did first, (b) the genre of imprecatory lament, (c) the lex talionis legal-theological framework.
The verse is not a command God endorses for individual / vigilante action. No biblical narrative shows an Israelite acting on Psalm 137:9 against Babylonian babies. The psalm hands the matter to God's judgment.
Christ's transformation is canonical. The NT explicitly transforms the imprecatory pattern: love of enemies; forgiveness; entrusting judgment to God. A Christian reads Psalm 137:9 through Christ, recognizing the genuine pain expressed, refusing to act on its content, and trusting God's justice.
The historical fulfillment in Babylon's fall. The psalmist's anticipation was historically realized: Babylon fell in 539 BC to Cyrus the Persian; the city was eventually utterly desolated (Isaiah 13-14; Jeremiah 50-51). The cry-for-justice was answered in God's providence, though not by a human Israelite agent.

"Dashing against the rock", the historical practice

The image of dashing infants against rocks is not unique to Psalm 137. It describes a documented ancient-Near-Eastern military atrocity:

Hosea 13:16, "the little ones [of Samaria] will be dashed in pieces" (Assyrian conquest)
Nahum 3:10, "her small children also were dashed to pieces" (Thebes destroyed)
2 Kings 8:12, Hazael will "dash in pieces their little ones"
Isaiah 13:16, 18, same fate prophesied for Babylon (the fulfillment of Psalm 137:9 anticipation)

The Hebrew text uses the verb nipets (to dash, smash), the same root as in these other passages. The image is borrowed from Babylon's own military practice (Babylon does this; Israel cries out that Babylon will receive it back). The psalm's force depends on the documented horror of what Babylon does to defeated peoples' infants, the cry is for measure-for-measure justice.

Patristic / scholarly note

Augustine (Enarrationes in Psalmos 137; Confessions I.6-7), the foundational allegorical / typological reading: the babies are nascent sins; the Rock is Christ; the dashing is the mortification of sin. This reading dominated patristic / medieval engagement with the verse, partly because the literal sense was so morally jarring within the Christian context of love-of-enemies ethics.

Modern conservative Reformed engagement: John Day (Crying for Justice: What the Psalms Teach Us About Mercy and Vengeance, 2005); James Adams (War Psalms of the Prince of Peace, 1991); Erich Zenger (A God of Vengeance? Understanding the Psalms of Divine Wrath, 1994; trans. 1996). Tremper Longman III (How to Read the Psalms, 1988); Walter Brueggemann (The Message of the Psalms, 1984), both treat the imprecatory psalms with sympathy for the lament-genre / honest-expression reading.

C. S. Lewis (Reflections on the Psalms, 1958), engages the imprecatory psalms candidly, calling them "terrible" and "diabolical" in their literal sense but recognizing the legitimate-anguish-of-victim that they preserve. Lewis's discussion is one of the most-cited literary-Christian treatments of the imprecatory problem.

Modern conservative apologetics: Paul Copan (Is God a Moral Monster?, 2011, ch. 12); Glenn Miller's A Christian Thinktank extensive online treatments; David Lamb (God Behaving Badly, 2011). All defend honest engagement with the imprecatory genre while refuting skeptical mischaracterization.

Apologetic significance

The verse, when honestly engaged, anchors:

The Bible's literary honesty about human anguish. Even the holy book preserves human anger and pain in their unvarnished form. This is a feature, not a bug.
The genre-recognition principle in biblical hermeneutics. Reading lament as command, descriptive as prescriptive, is hermeneutically irresponsible. The skeptical use of Psalm 137:9 typically commits this category error.
The progressive-revelation trajectory in canonical theology. The OT cry-for-justice is canonically transformed (not abolished) in NT love-of-enemies / Christ-on-cross / final-judgment theology.
The historical context of ancient warfare. ANE warfare was systematically brutal; the psalmist's cry is shaped by what was actually done to Israel's children. Reading the verse outside this context produces caricature.
The pastoral validity of lament. Imprecatory psalms validate the legitimacy of grief, anger, and longing for justice as expressed to God in prayer. Survivors of atrocity may pray this honestly while still trusting God's justice and Christ's transformation.
