Commentary on Isaiah 51:1-6

During difficult times, many of us look for people, relationships, or objects that ground us. We often seek reminders that amid changing and uncertain times, there is something (or someone) that is constant, dependable, and trustworthy. 

As a child in church, I remember hearing testimonies and songs that juxtaposed the constancy of God with the unpredictability of life. In the African American churches I have called home, God’s history of faithfulness was a foundation for our collective identity as a people and our present hope. “Didn’t my Lord deliver Daniel … why not every man?” was a refrain that regularly lifted spirits, encouraged souls, and inspired actions. Our text in Isaiah 51:1–6 follows a similar pattern of reminding the nation of their origins, God’s history with them, and how both become sources of hope amid changing and uncertain times.

A Godly past

Isaiah 51:1b tells the nation to “look (nabat) to the rock (tzur) from which you were hewn.” The instruction to look does not just mean to see, but to be attentive to what one is viewing. By attending to the rock that is identified as a raw material for the nation, they are reminded that the nation, like the rock out of which they were cut, is strong, stable, and sure, especially amid changing and uncertain times. The author continues this appeal to the nation’s origins as a source of strength and a reminder of God’s faithfulness by invoking God’s relationship with Abraham and Sarah (Isaiah 51:2). This verse reminds the nation that their very existence is evidence of God’s fidelity and power to fulfill divine promises. 

Though Abraham “was but one when I called him” (Isaiah 51:2), God’s blessing and provision took one couple and made their descendants into a nation. Like many prophetic texts, the nation is exhorted to have confidence in God’s present deliverance because they know (or should remember) the stories of God’s past salvation. Moreover, the passage invokes God’s creative perfection that Eden embodied as an indication of what God can (and will) do for this people (Isaiah 51:3a). Perhaps most importantly for a decimated community, the authors of Isaiah remind the audience that the God who created Eden will transform the nation’s present wilderness into this idyllic “garden of the LORD.” 

The dire circumstances of this present predicament do not reflect a decline in God’s power or purpose. As Hebrews 13:8 declares, God is “the same yesterday, today, and forever.” This constancy of character provides confidence that God’s conduct will be consistent across time—a hope that the remaining verses describe. 

A hope-filled future

The invocation of Eden frames a series of promises of restoration God makes to the nation. During the challenges Neo-Babylonian domination presents, the author reminds the people of God’s commitments to comfort Zion and bring her citizens joy and gladness (Isaiah 51:3). In Isaiah 51:3, the authors emphasize that God’s deliverance is coming quickly and drawing closer. Thus, the reversal of the nation’s fortunes is not a promise for some distant time or an unborn generation. Rather, it is imminent and, by implication, the citizens of Judah should prepare themselves for God’s movement. 

Like other passages in the concluding chapters of Isaiah (for example, Isaiah 56), the restoration of Israel has multiple functions. One of the functions is that Israel becomes a beacon of God’s justice and righteousness not just to Israel but “to all nations” (Isaiah 51:4–5). Although God’s redemptive actions commenced with Israel, they are neither controlled by nor contained to Israel. 

Thus, the transformation of Israel is a quasi-downpayment on God’s work for the benefit of all creation. Indeed, the impending eruption of God’s righteousness and salvation into history is the only enduring reality upon which the nation can rely. According to Isaiah 51:6, the heavens, earth, and its inhabitants will not last. Rather, God announces, “My salvation will be forever, and my deliverance will never be ended (teꜧat)” (Isa 51:6b). 

This concluding verse emphasizes that salvation and deliverance have one owner—God. As a result, the nation should not look to any other source for God’s redemptive work. Additionally, the authors record that God’s deliverance will not be ended (teꜧat). The Hebrew term translated as “ended” can also mean to be broken or shattered. At a time when the nation feels broken, shattered, and scattered, God’s concluding promise encourages the nation that God’s deliverance endures and will not be broken. 

The surety of the unbreakable promise of God’s deliverance points back to the rock and quarry at the beginning of this passage out of which God formed the nation. God formed the nation from a material that endures, and God will restore the nation with something even more durable—namely, God’s salvation and deliverance. 

A present reminder

Within Christian traditions, Isaiah 51 appealing to a rock as the source or raw material constituting God’s community is reminiscent of the Matthew 16 passage included in this week’s lectionary readings. For both communities, stability, surety, and safety can be found in remembering one’s relationship with The Rock who is their foundation. Whether in the tumult of the sixth century BCE, the turbulence of the first century CE, or the tempests of the 21st century CE, God invites God’s people to remember their source. This remembrance, in turn, frames how they conceive of their identity and relationship to an ever-changing (and often violent) world. 

In the biblical contexts, the institutions of God’s righteousness and salvation are described as the only sure, certain, and appropriate object of the people’s attention. In our modern world, the church is invited to join these millennia-old choruses to remind people of what and who will endure.
