Isaiah 51:8

For the moth will devour them like a garment, and the worm will eat them like wool. But My righteousness will last forever, My salvation through all generations."

Study Bible

For the moth will eat them up like a garment
The imagery of a moth consuming a garment is a powerful metaphor for the transient nature of human power and glory. In the Hebrew context, the moth (Hebrew: עש, 'ash) is a symbol of decay and destruction, often used in the Bible to illustrate the frailty and impermanence of earthly things. Just as a moth quietly and persistently destroys fabric, so too will the seemingly strong and enduring structures of human pride and sin be reduced to nothing. This serves as a reminder of the futility of relying on worldly strength and the importance of seeking eternal values.

and the worm will devour them like wool
The worm (Hebrew: רמה, rimmah) further emphasizes the theme of decay. In ancient times, wool was a valuable commodity, representing wealth and status. The worm's consumption of wool signifies the inevitable decline of material wealth and human achievements. This phrase underscores the biblical teaching that earthly treasures are vulnerable to corruption and loss, as seen in Matthew 6:19-20, where believers are encouraged to store up treasures in heaven. The imagery calls believers to focus on spiritual riches that are imperishable.

But My righteousness will last forever
In stark contrast to the temporary nature of human endeavors, God's righteousness (Hebrew: צדקה, tsedaqah) is eternal. This righteousness is not merely a moral attribute but encompasses God's faithfulness, justice, and covenantal promises. The assurance that God's righteousness will endure forever provides comfort and hope to believers, affirming that God's character and His commitment to His people are unchanging. This eternal righteousness is a foundation upon which believers can build their lives, knowing that it will never fail or fade.

My salvation through all generations
The promise of salvation (Hebrew: ישועה, yeshu'ah) extending through all generations highlights the perpetual and inclusive nature of God's redemptive plan. Salvation is not limited to a single time or people but is available to all who trust in God across the ages. This phrase reassures believers of the continuity of God's saving work, which began with the patriarchs, was fulfilled in Christ, and continues through the Holy Spirit's work in the Church. It invites believers to participate in this ongoing account of redemption, confident in the knowledge that God's saving grace is as relevant today as it was in the past.
