Isaiah 1:21 – “See how the faithful city has become a prostitute! She once was full of justice; righteousness used to dwell in her—but now murderers!”
An Extended Explanation of the Verse
Isaiah 1:21 laments the moral and spiritual decay of Jerusalem, referred to as “the faithful city.” Once a place characterized by justice and righteousness, Jerusalem has become corrupt and unfaithful, likened to a prostitute. This comparison reflects the city’s betrayal of its covenant relationship with God. Instead of living in obedience to Him and serving as a light to the nations, Jerusalem had become a place of violence, injustice, and moral compromise.
The phrase “she once was full of justice” highlights the stark contrast between the city’s former glory and its current state. The reference to “murderers” emphasizes the depth of the corruption, showing that the city has strayed far from God’s design for His people. This verse captures both the sorrow of what has been lost and the gravity of the people’s rebellion.
Historical Context
Isaiah’s ministry took place during a time when Judah, and particularly Jerusalem, was in spiritual decline. Although the people continued their religious rituals, their hearts were far from God. Leaders and officials were exploiting the poor, the judicial system was corrupt, and idolatry was widespread.
Jerusalem, as the center of worship and governance, was meant to reflect God’s character of justice and righteousness. Instead, it had become a place of oppression and sin. The imagery of prostitution echoes themes from the covenant, where Israel’s relationship with God is likened to a marriage (Jeremiah 3:1-3, Hosea 2:2-5). By turning to idolatry and injustice, Jerusalem had been unfaithful to God, breaking their covenant relationship.
Theological Implications
This verse underscores the seriousness of sin and its consequences. Sin is not just a violation of rules; it is a betrayal of relationship. By turning away from God, the people of Jerusalem had abandoned their identity and purpose as His chosen people.
The verse also highlights the transformative power of sin. A city once known for justice and righteousness had become characterized by murder and corruption. This reminds us that sin, left unchecked, leads to a complete reversal of God’s intended order.
Yet, this verse also reflects God’s heart for His people. The lament over Jerusalem’s unfaithfulness shows that God cares deeply about their relationship and longs for their restoration.
Literary Analysis
Isaiah 1:21 uses vivid imagery and strong contrasts to convey its message. The metaphor of the “faithful city” becoming a “prostitute” is shocking and provocative, intended to grab the reader’s attention. It reflects both the depth of Jerusalem’s sin and the pain of God’s betrayal.
The juxtaposition of “justice” and “murderers” highlights the drastic change in the city’s character. The parallel structure—what Jerusalem “once was” versus what she “now” is—emphasizes the tragedy of her fall. This poetic technique evokes both sorrow and urgency, compelling the audience to consider the consequences of unfaithfulness.
