Isaiah 31

Today’s Passage: Isaiah 31

Once again Isaiah lifts his voice against the great temptation of his day, the temptation of a small kingdom under threat to buy its safety from a stronger one. Judah was looking south to Egypt, to her famous horses and her clattering chariots and her ranks of horsemen, hoping that so much muscle and metal would hold the Assyrian storm off. The prophet answers with a solemn woe, then with a picture so tender it can hardly be believed: the same LORD who is like a lion no shepherd can frighten will come down to fight for Mount Zion, and He will hover over Jerusalem the way a mother bird spreads herself over the nest. Between the warning and the comfort stands the one thing Judah has forgotten to do, and Isaiah names it plainly: return to the God against whom you have so grievously rebelled.

As you read, hold this: To lean on the arm of flesh while ignoring the Holy One is folly, for the living God Himself will fiercely defend and tenderly shelter all who return to Him.

Isaiah 31:1 (BSB)

¹ Woe to those who go down to Egypt for help, who rely on horses, who trust in their abundance of chariots and in their multitude of horsemen. They do not look to the Holy One of Israel; they do not seek the LORD.

The woe falls not on the horses but on the trusting of them. Notice how carefully Isaiah lays out the two halves of the sin, for they always travel together. On one side there is what these men do: they go down to Egypt, they rely on horses, they trust in the sheer abundance of chariots and horsemen, counting up the strength they can see and lean on. On the other side there is what they fail to do: they do not look to the Holy One of Israel, they do not seek the LORD. That is the heart of it. The tragedy is not that they made a plan but that they made a God-shaped hole in it, reaching for the arm of flesh precisely where they should have reached for the arm of heaven. A man may prepare and still trust God; but to trust the preparation instead of the God who gives every victory is to build one’s whole hope on sand.

Isaiah 31:2–3 (BSB)

² Yet He too is wise and brings disaster; He does not call back His words. He will rise up against the house of the wicked and against the allies of evildoers. ³ But the Egyptians are men, not God; their horses are flesh, not spirit. When the LORD stretches out His hand, the helper will stumble, and the one he helps will fall; both will perish together.

There is a quiet, cutting irony in the way Isaiah says that God, too, is wise. The schemers in Jerusalem thought themselves shrewd for securing so mighty an ally, but the LORD is wiser still, and unlike them He never has to take back His word or revise His plan. Then comes the sentence that ought to be written over every anxious heart that has ever trusted in something it could see and touch: the Egyptians are men, not God; their horses are flesh, not spirit. Feel the weight of that contrast. On the one hand, flesh (בָּשָׂר) basar, pronounced bah-SAR. Strong's H1320, flesh, body, mortal creaturely being. When Isaiah sets Egypt’s horses down as basar and not ruach, spirit, he is drawing the oldest line in all of reality, the line between the creature and the Creator. Flesh gets tired. Flesh bleeds. Flesh is here for a season and then is not. To lean the full weight of your hope on flesh, however impressive the muscle and the numbers, is to lean on a thing that was never made to hold you. The whole Bible presses this contrast on us so that we will stop looking to the strong arm we can see and start looking to the God whose Spirit made and upholds it all. Blessed is the one who has learned that flesh is not spirit, and that only the living God is a rock beneath the feet. : mortal, tiring, breakable, here today and gone. On the other, spirit: the living, unwearied, almighty God. When He merely stretches out His hand, the mighty helper stumbles and the one who leaned on him falls, and both go down together in a single ruin. The lesson is not that horses are worthless but that they are creatures, and no creature, however strong, can bear the weight that belongs to God alone.

Isaiah 31:4–5 (BSB)

⁴ For this is what the LORD has said to me: “Like a lion roaring or a young lion over its prey—and though a band of shepherds is called out against it, it is not terrified by their shouting or subdued by their clamor—so the LORD of Hosts will come down to do battle on Mount Zion and its heights. ⁵ Like birds hovering overhead, so the LORD of Hosts will protect Jerusalem. He will shield it and deliver it; He will pass over it and preserve it.”

Now the prophet gives us two of the most striking pictures of God in all of Scripture, set side by side, and we should let both of them do their work. First the lion. Imagine a great lion standing over its prey, and a whole band of shepherds rushing out with shouts and noise to drive it off, and the lion simply lifting its head, unmoved, undismayed, not budging an inch for all their clamor. So, says the LORD, will I come down to fight for Mount Zion, unshaken by anything arrayed against Me. Then, in the very next breath, the picture turns from fierce to tender. Like birds hovering over the nest, the LORD of Hosts will spread Himself over Jerusalem, shielding, delivering, passing over and preserving her. That word passing over carries a memory of the Passover night in Egypt, when the LORD guarded His people while judgment swept by. Here is the wonder of the God Judah forgot to seek: He is both the lion no army can frighten and the mother bird whose wings cover the weak. His fierceness and His tenderness are not two Gods but one, and both are turned toward the protection of His own.

Isaiah 31:6–7 (BSB)

⁶ Return to the One against whom you have so blatantly rebelled, O children of Israel. ⁷ For on that day, every one of you will reject the idols of silver and gold that your own hands have sinfully made.

Right at the center of the chapter comes the one word that everything has been driving toward: return. It is the great gospel word of the prophets, and it lands here with disarming gentleness. Return, He says, to the very One against whom you have rebelled so openly. There is grace hidden in that call, for the God who has every right to turn away is instead holding the door open and inviting the rebels home. And Isaiah promises that a day is coming when this turning will be real, when the people will fling away the little idols of silver and gold their own hands had shaped, ashamed at last of the powerless things they had preferred to the living God. This is what repentance always looks like: not merely feeling sorry, but turning from the false helpers we have made and running back to the true Helper we had left. The horses of Egypt and the idols of the workshop are cut from the same cloth, both of them the work of human hands, both of them trusted where God should have been trusted, and both of them fit only to be forsaken.

Isaiah 31:8–9 (BSB)

⁸ “Then Assyria will fall, but not by the sword of man; a sword will devour them, but not one made by mortals. They will flee before the sword, and their young men will be put to forced labor. ⁹ Their rock will pass away for fear, and their princes will panic at the sight of the battle standard,” declares the LORD, whose fire is in Zion, whose furnace is in Jerusalem.

The chapter closes by settling the whole question Judah had been so anxious about. Assyria, the terror that had sent everyone scrambling to Egypt, will indeed fall, but mark how: not by the sword of man, not by any weapon Egypt’s cavalry could have supplied. A sword not made by mortals will devour her. In other words, the very deliverance the leaders had gone hunting for in the south would be given, freely and finally, by the God they had failed to seek at home. History would prove it true when Assyria’s great army melted away in a single night without Judah lifting a hand. Even the enemy’s rock, whatever they had trusted in, would crumble in fear, and their proud princes would panic at the mere sight of the battle flag. And the last line names the reason for it all: the LORD, whose fire is in Zion, whose furnace is in Jerusalem. The God they were tempted to abandon was the very furnace of holiness dwelling in their midst, the one sure defense they had almost traded away for horses. They had gone looking down to Egypt for a rescue that was standing all the while at the center of their own city.
