The Book of Isaiah: The Holy One of Israel

Isaiah 20

Today’s Passage: Isaiah 20

This short chapter steps out of poetry and into plain history for a moment, and it does something we do not often see a prophet asked to do. The LORD does not merely give Isaiah words to say; He gives him a picture to become. Assyria has marched against the Philistine city of Ashdod and taken it, and against that backdrop the LORD tells Isaiah to lay aside the rough garment of a prophet and go about stripped and barefoot, the way a prisoner of war is stripped and driven off. For three years he walks like this through Jerusalem, a living sermon that no one can ignore, and then the LORD tells the meaning of it: just so will Assyria lead away Egypt and Cush, the very powers that little Judah was tempted to lean on for rescue. It sits here among the oracles about the nations as a pointed word to God’s own people, aimed straight at the hope they had placed in the wrong place.

As you read, hold this: It is folly to pin our hope of rescue on worldly powers, however impressive, for they cannot finally save; the only sure refuge is the LORD.

Context The world of Isaiah 20

In these years the shadow of Assyria lay over the whole region, and the small kingdoms along the coast were forever plotting how to survive it. The obvious strategy, and the tempting one, was to look south to Egypt, the old and mighty river-kingdom, and to Cush beyond it, and to hope that such a power could stand between them and the Assyrian armies. Ashdod was one of the Philistine cities caught up in exactly this kind of scheming, and when it rebelled, Sargon of Assyria sent his chief commander, who came and took the city. That is the hard fact standing behind Isaiah’s strange three years: the nations were choosing their protectors, and Judah was watching, and its heart was drifting toward Egypt too.

The sign Isaiah is given must be understood for what it is. This is not indecency, and it is not the prophet shaming himself for its own sake. It is a solemn prophetic sign, the way Ezekiel later lay on his side and Jeremiah wore a yoke, a picture acted out in the body so the truth could not be argued away. To go stripped of the outer sackcloth and barefoot was to look like a captive being marched into exile, and that is precisely the point. Isaiah wears the coming fate of Egypt and Cush on his own person, so that when Judah looked at him walking the streets, they were looking at what would become of the very nations they were counting on to save them.

Isaiah 20:1–2 (BSB)

¹ Before the year that the chief commander, sent by Sargon king of Assyria, came to Ashdod and attacked and captured it, ² the LORD had already spoken through Isaiah son of Amoz, saying, “Go, remove the sackcloth from your waist and the sandals from your feet.” And Isaiah did so, walking around naked and barefoot.

Notice first how careful the text is to fix this in real time and real place. There is a named king, a named campaign, a captured city, so that no one could ever mistake this for a fable. Into that concrete moment the LORD speaks, and what He asks of His servant is costly and humbling. Isaiah is to lay aside the coarse garment that marked him as a prophet and walk the city stripped and barefoot, taking on the appearance of a man led away in defeat. And what strikes me most is the single quiet line at the end: and Isaiah did so. There is no recorded protest, no bargaining, only obedience. He was willing to become the sermon, to carry a hard word in his own body for three long years, because the message mattered more than his comfort or his dignity. That is the mark of a true servant of God, that when the word is given, he does it.

Isaiah 20:3–4 (BSB)

³ Then the LORD said, “Just as My servant Isaiah has gone naked and barefoot for three years as a sign and omen against Egypt and Cush, ⁴ so the king of Assyria will lead away the captives of Egypt and the exiles of Cush, young and old alike, naked and barefoot, with bared buttocks—to Egypt’s shame.

Now the picture is given its meaning, and the LORD calls Isaiah “My servant,” a title of honor laid upon the man who was willing to be humbled. The sign points outward to Egypt and Cush, the twin powers of the south, and the message is plain and sobering: what Isaiah looks like now is what those proud nations will look like soon. The mighty will be led away like the lowest captive, young and old together, stripped and shamed, driven along a foreign road. We should read this soberly and without any gloating, for there is no delight to be taken in the humbling of anyone. Yet we must not miss what the LORD is teaching through it. The nation Judah was tempted to trust as a wall against Assyria would itself be swept away in the flood. The protector could not protect. The strong arm men were reaching for would be bound behind its own back.

Isaiah 20:5 (BSB)

⁵ Those who made Cush their hope and Egypt their boast will be dismayed and ashamed.

Here the word turns and comes home, and it lands on the heart. Look at the two verbs the LORD uses for what Egypt and Cush had become to their admirers: their mivtach, pronounced miv-TAKH. Strong's H4009, confidence, trust, the object of one's trust. This is a rich and searching word. Mivtach is not a passing wish or a faint preference; it is the object of one’s confidence, the thing a person leans the full weight of the soul upon, that in which one places trust for safety. It comes from the root batach, to trust, to feel secure, to be confident. And the whole burden of Scripture is that everything depends on where this mivtach is set. Israel had let Egypt become their mivtach, and Isaiah says such trust ends in dismay, for a nation of chariots and horses, however grand, is a foundation of sand. The same word, though, is turned the right way elsewhere: blessed is the man whose mivtach is the LORD. Here is the great sorting of every human heart, that we are all leaning our confidence on something, and only one refuge will still be standing when the storm has passed. and their boast. These nations were not merely allies of convenience; they had become the thing men leaned their whole confidence upon, the thing they bragged about when fear crept in, the answer they gave themselves in the dark. And the promised end of all such misplaced confidence is dismay and shame. That is always how it goes when we make anything less than God our final refuge. For a time the boast feels solid, the strong ally looks unshakable, and then the day of testing comes and the thing we trusted proves it cannot save, and we are left ashamed that we ever bowed our hope so low. The tragedy is not that Egypt was weak, but that hearts made for God had come to rest in Egypt at all.

Isaiah 20:6 (BSB)

⁶ And on that day the dwellers of this coastland will say, ‘See what has happened to our source of hope, those to whom we fled for help and deliverance from the king of Assyria! How then can we escape?’”

The chapter ends with a cry, and it is the cry of people who have watched their confidence collapse. The dwellers of the coastland look at the ruin of Egypt and Cush and speak the bitter truth aloud: See what has become of our source of hope, the very ones we fled to for rescue. And then comes the question that has no answer for them, How then can we escape? It is the sound of a soul that trusted the wrong thing and now has nowhere left to run. Yet even in that cry there is a mercy hidden for anyone with ears to hear, because the question exposes the folly plainly enough that we need not repeat it. If the powers of the earth cannot finally save, then the wise thing, the only truly safe thing, is to flee not to Egypt but to the God who made Egypt, to the Holy One of Israel who never fails those who take shelter in Him. The coastland asks how they can escape; the answer their whole history was meant to teach them was standing over them all along, waiting to be their refuge.

Study notes Going deeper

The lesson of Isaiah 20 is not tied to one ancient empire or one long-vanished alliance. It reaches into every age and every heart, because the temptation it exposes never dies. We are all forever tempted to make some visible, impressive thing our mivtach, our source of security, whether it be a strong nation, a full bank account, a powerful friend, our own cleverness, or the plans we have laid so carefully. Isaiah’s three silent years in the street say to all of it the same steady word: these cannot finally save you. And the Psalms take up the very same warning and press it home.

"Put not your trust in princes, in mortal man, who cannot save." Psalm 146:3 (BSB)

Mortal man cannot save, and neither can the mightiest works of mortal man. That is not a counsel of despair; it is a door thrown open. For the same Scriptures that tear down our false refuges do it only to lead us to the true one, to the LORD who is himself an everlasting refuge, whose arm does not shorten and whose promises do not fail. Set your mivtach there, on the Holy One of Israel, and when every earthly hope has been led away stripped and barefoot, you will still be standing, sheltered and unashamed. Learn the Word, set your trust where it can never be put to shame, and give thanks.
