In the kitchen, some food substitutions work better than others. Swap oil for applesauce? Sure! Use almond or soy milk for your lactose-sensitive friends? Unnoticeable. Cut some butter in favor of plain yogurt? Absolutely.
But other replacements don’t cut the mustard. Gluten-free bread doesn’t behave like bread. Fat-free cheese won’t melt. Tofu? No thanks.

But the altar is unlike the oven. Though we know nothing measures up to God, our hearts are prone to wander. How does God react to his children’s idolatry? Isaiah 31:1–9 gives us a glimpse.
The Alliance With Egypt
In a previous post we saw Judah seek protection from Assyria through a sinful alliance with Egypt. Isaiah tells us that Judah turned to “horses,” “chariots,” and “horsemen” instead of looking to God (Is 31:1). Why did Judah trust Egypt? What are the consequences of that misplaced trust?
Isaiah writes that Judah “trust[s] in chariots because they are many and in horsemen because they are very strong” (Is 31:1). Were the chariots and horsemen of Egypt really stronger and more able than God? Judah’s betrayal was that they did “not look to the Holy One of Israel, or consult the Lord.”
God’s reaction to this treason springs from his character: he is “wise” and he “does not call back his words” (Is 31:2). He will turn against Egypt, the “helpers” who “work iniquity.” We read the obvious contrasts: “the Egyptians are man, and not God, and their horses are flesh, and not spirit” (Is 31:3). Isaiah highlights these disparities both to emphasize the inability of Egypt to resist “when the Lord stretches out his hand” and to finish the rebuke begun in Is 31:1.
Notice that Egypt and Judah share a fate: “they will all perish together” (Is 31:3). As we saw when studying Isaiah 30, God often punishes sin by bringing about its natural consequences. Judah sinned by aligning with Egypt, so they will share Egypt’s demise. The alliance they pursued for life has resulted in death.
Like a Lion, Like Birds
We read of two similies for God’s posture toward his people in Is 31:4–5. In Is 31:4, Isaiah compares God to a lion who “growls over his prey.” The “band of shepherds” (Egypt) tries to rescue the prey (Judah) from the lion, but the lion “is not terrified by their shouting or daunted at their noise.”
Does it bother you that God compares Judah to a lion’s prey? God is jealous for his people—he will discipline them as he pleases, with no unwanted interference.
This same “Lord of hosts” (repeated in Is 31:4 and Is 31:5) who will wage war on Mount Zion (Is 31:4 NASB) will also protect Jerusalem like hovering birds. God will “protect and deliver” and “spare and rescue” his people, a fourfold blessing of protection.
A natural question is, from whom/what is God delivering Judah? On the one hand, God is rescuing his people from their earthly enemies. But put these two figures together—if Judah is like a lion’s prey, then God is also sparing Judah from himself.
Can you see your Savior here? In Jesus, God rescues us from his own just wrath. The Father spares us by devouring his son like lion’s prey. We are protected because Jesus was not.
Turn to God!
In Is 31:6 NASB, Isaiah exhorts Judah to return to God from whom they have “deeply defected.” What an accusation! Defected means Judah has not merely forgotten God or somehow grown apathetic, but they have turned against him! A defector doesn’t quit military service, he wages war against his former allies. “Defector” is the charge leveled against idolators. If we worship anything other than God (and we do), we are traitors.
Isaiah tries to persuade Judah to return to God in Is 31:7 by writing that “everyone shall cast away his idols.” Is this a convincing argument?
There is no doubt about the sinfulness of idols: we see “idols” twice along with “sinful” and “sin” in Is 31:7 NASB. But the glory of the Lord will be so great “in that day” that “everyone” will discard their idols. If that is true about this glorious, future day, why not start now? You’ve defected from him—waste no time in turning back!
God Fights for His Own
Along with a return to God and the smashing of idols, in that day “the Assyrian shall fall” (Is 31:8). We saw God’s willingness to fight for his people in Is 30:32 and we see it again here with the repetition of “a sword, not of man.” God’s sword will slay the Assyrian.
In addition to death, God will bring slavery, panic, and terror to the Assyrians (Is 31:8–9). God is not to be opposed. If you wage war against his people, you may feel his “fire” or be subject to his “furnace” (Is 31:9).
Return to God through his Son
Isaiah’s message is clear. Do not trust in replacements for God. Return to God—he will discipline, protect, and deliver his people. But we take no Christian meaning from the chapter unless we consider Jesus.
Jesus died for our idolatry. The Lord “stretch[ed] out his hand” against Jesus in terrible judgment. Though he had opportunity (Matt 4:1–11), Jesus never (not once!) trusted anyone except his Father.
Jesus makes it safe for deep defectors to return to God. Because Jesus (the faithful, loyal one) was treated as a traitor, we are welcomed as sons and daughters of God. For those who are in Christ, we are no longer enemies of God, and God will take vengeance on our behalf (Rom 12:19).
Application
Consider these questions as you apply the truths of this chapter.
- How can we identify our replacements for God? How can we help each other identify these replacements?
- What are the barriers we might face to helping each other in this way?
- How should we call each other to return to God? How can we be the sort of people that can be called back to God by our friends?
