Text

“Therefore now hear this, you afflicted one, drunk, but not with wine.” (Isaiah 51:21)


Literary Setting and Immediate Context

Verses 17-23 form a single oracle within Isaiah 51. Jerusalem is pictured as a woman who has drained “the cup of His fury” (v.17). Verse 21 bridges from the description of judgment (vv.17-20) to the promise that God Himself will remove the cup (vv.22-23). The command “hear” marks a new address, inviting the hearer to move from despair to hope.


Theme 1: Divine Wrath as Disciplinary Judgment

The phrase “drunk, but not with wine” signifies staggering under God’s wrath rather than literal intoxication. Scripture consistently portrays divine wrath as righteous, measured, and covenantal (Leviticus 26; Deuteronomy 28; Lamentations 4:21). Isaiah’s imagery exposes Judah’s sin while affirming that God’s judgment is purposeful discipline, not capricious anger (Hebrews 12:5-11).


Theme 2: The Cup Motif in Biblical Theology

The “cup” is a trans-canonical symbol of judgment (Psalm 75:8; Jeremiah 25:15-17; Revelation 14:10). In Isaiah 51:17-23, Judah drinks the cup; in the Gospels, Christ volunteers to drink it in their stead (Matthew 26:39; Luke 22:42), fulfilling substitutionary atonement (2 Corinthians 5:21). The passage thus foreshadows the redemptive exchange central to the gospel.


Theme 3: Covenant Relationship and Divine Ownership

Calling Judah “afflicted one” (ʿănîyâh) evokes God’s covenant name and compassionate concern (Exodus 3:7). Discipline occurs within covenant, ensuring that wrath never nullifies God’s promises to Abraham and David (Genesis 17:7; 2 Samuel 7:14-16). Isaiah 51:21 therefore assumes an unbroken covenant, later ratified in the New Covenant (Jeremiah 31:31-34; Luke 22:20).


Theme 4: Divine Compassion and Consolation

The transition from judgment (vv.17-20) to comfort (vv.22-23) highlights God’s steadfast love (ḥesed). Multiple imperatives—“listen,” “awake,” “hear”—invite the afflicted to believe that mercy follows chastisement (Psalm 30:5). This pattern recurs throughout Isaiah (40:1; 54:7-8) and culminates in Revelation 21:4.


Theme 5: Reversal of Fortune and Eschatological Hope

God promises to transfer the cup “to those who tormented you” (v.23). This anticipates the eschatological reversal described in Isaiah 60-66 and echoed in Christ’s Beatitudes (Matthew 5:3-12). The afflicted become victors; oppressors become recipients of justice (2 Thessalonians 1:6-10).


Theme 6: Messianic Foreshadowing and the Suffering Servant

Isaiah 51 sets the stage for the Servant Songs (Isaiah 52:13-53:12). The afflicted Jerusalem prefigures the Servant who bears wrath vicariously. New Testament writers see Isaiah’s language fulfilled in Christ’s passion (Acts 8:32-35; 1 Peter 2:24). The cup He drinks in Gethsemane secures the removal of Jerusalem’s cup in Isaiah.


Theme 7: Remnant Theology

The address is to a faithful minority within apostate Israel. Isaiah 10:20-23 and Romans 11:5 identify this remnant as the channel of God’s ongoing saving purpose. Isaiah 51:21 comforts the remnant that their suffering is temporary and redemptive.


Theme 8: Exhortation to Hearing and Obedience

“Therefore now hear this” calls for volitional response. The Hebrew verb שִׁמְעִי (shimʿî) carries the idea of hearing with the intent to obey (Deuteronomy 6:4). The New Testament reiterates that faith comes by hearing (Romans 10:17) and that obedience proves genuine faith (James 1:22).


Theme 9: God’s Sovereignty and Faithfulness

The sovereign initiative—God speaks, God judges, God rescues—underscores monotheistic theology (Isaiah 45:5-7). The afflicted contribute nothing but need; Yahweh supplies grace, echoing the doctrine of sola gratia (Ephesians 2:8-9).


Historical and Manuscript Corroboration

• The Great Isaiah Scroll (1QIsᵃ, c. 125 BC) contains Isaiah 51 with wording almost identical to modern Hebrew texts, underscoring textual stability.

• The Ketef Hinnom silver scrolls (7th century BC) confirm priestly blessing formulas echoed in Isaiah’s comfort oracles.

• Archaeological layers of Babylonian destruction (586 BC) at Jerusalem’s City of David align with the historical backdrop of Isaiah’s later chapters, giving weight to the prophecy’s setting.


Practical and Pastoral Implications

Believers today may feel “drunk, but not with wine” under life’s pressures. Isaiah 51:21 assures that such affliction is neither random nor final. Christ has drunk the ultimate cup; therefore, the bitter cup in the believer’s hand is transient and purifying (2 Corinthians 4:17).


Evangelistic Application

For the skeptic: empirical manuscript evidence, fulfilled prophecy, and the historical resurrection of Jesus (1 Corinthians 15:3-8) collectively validate the claim that the same God who spoke in Isaiah still speaks. The invitation stands: “Hear this.” Repentance and faith transfer the cup of wrath to Christ, replacing it with the cup of salvation (Psalm 116:13).


Conclusion

Isaiah 51:21 weaves together themes of righteous wrath, covenant love, substitutionary redemption, eschatological hope, and divine sovereignty. The afflicted are summoned to hear, trust, and anticipate restoration—a message ultimately realized in the finished work of the risen Christ and awaiting consummation in His return.
