Verse-by-Verse Commentary
The Book of Isaiah
Chapter 20: The Sign of the Naked Prophet
This short chapter is a living sermon. At God's command Isaiah takes off his sackcloth and his sandals and walks 'naked and barefoot' for three years, a shocking, humbling sign-act with a plain meaning: just so would Egypt and Ethiopia be led away stripped and barefoot by the king of Assyria. The nations that Judah and her neighbors were tempted to trust for rescue would themselves be dragged off in shame. The chapter ends with the sinking question of everyone who leaned on the wrong thing: 'how shall we escape?'

The Sign of the Naked Prophet (Isaiah 20:1-2)
In the year Assyria took Ashdod, God commands Isaiah to strip off his sackcloth and sandals and walk naked and barefoot, and the prophet obeys.
Go and Loose the Sackcloth
"In the year that Tartan came unto Ashdod, (when Sargon the king of Assyria sent him,) and fought against Ashdod, and took it; At the same time spake the LORD by Isaiah the son of Amoz, saying, Go and loose the sackcloth from off thy loins, and put off thy shoe from thy foot. And he did so, walking naked and barefoot."
Hebrew Study
"a sign," oth (אוֹת). A sign is something that points beyond itself to a meaning. Isaiah's strange action was exactly that, a walking, visible message that no one in Jerusalem could ignore.
"wonder," mopheth (מוֹפֵת). A wonder is a startling, attention-seizing marvel. Isaiah was this as well as an oth: the two words stand together, "a sign and wonder."
"naked," arom (עָרוֹם). The word need not mean fully unclothed; it commonly describes a person stripped down to an undergarment or loincloth, as a slave or prisoner of war would be. Isaiah went about dressed like a captive, dramatizing the very captivity he foretold.
Explanation
The chapter opens with a fixed historical marker: "the year that Tartan came unto Ashdod," when Sargon king of Assyria sent his commander to besiege and take that Philistine city (around 711 BC). Assyria was on the march, and the small nations of the region, including Judah, were tempted to look to Egypt and Ethiopia for protection. Into that moment God gives Isaiah a strange command: "Go and loose the sackcloth from off thy loins, and put off thy shoe from thy foot." And the prophet obeyed, "walking naked and barefoot." Stripped to the clothing of a captive, Isaiah became a living billboard walking the streets of Jerusalem.
Gospel Focus
Consider the obedience this took. Isaiah was a respected prophet, and God asked him to spend three years in public humiliation, dressed like a prisoner, to make a point. He "did so." He did not argue that it was beneath his dignity or ask for an easier assignment. God's servants have often been called to obey in costly, humbling ways: Ezekiel lay bound on his side, Hosea married a faithless wife, and the prophets bore in their own bodies the message they preached. The gospel asks the same willingness of us, to obey even when obedience costs our comfort or our reputation. Jesus Himself "made himself of no reputation" and was stripped and shamed for our sake. If God calls you to a hard or humbling obedience, remember Isaiah, who simply "did so," and trust that a God who asks much has a purpose worth far more than the dignity we surrender to Him.
A Sign Against Egypt and Ethiopia (Isaiah 20:3-4)
God explains the sign: as Isaiah walked stripped and barefoot, so Assyria would lead Egypt and Ethiopia away captive, to the shame of the nations Judah was trusting.
Three Years for a Sign and Wonder
"And the LORD said, Like as my servant Isaiah hath walked naked and barefoot three years for a sign and wonder upon Egypt and upon Ethiopia; So shall the king of Assyria lead away the Egyptians prisoners, and the Ethiopians captives, young and old, naked and barefoot, even with their buttocks uncovered, to the shame of Egypt. And they shall be afraid and ashamed of Ethiopia their expectation, and of Egypt their glory."
Hebrew Study
God turns Isaiah himself into a living sign (oth): the prophet walks "naked and barefoot three years" as a walking parable that the king of Assyria will lead away the Egyptians and Ethiopians as captives, "naked and barefoot," to their shame. The prophets were sometimes called to enact their message at personal cost, embodying it so vividly that it could not be ignored. Isaiah's humiliating sign-act was a mercy — a dramatic warning to Judah not to lean on Egypt, whose own doom he wore before their eyes.
Explanation
Now God gives the meaning of the sign. Isaiah's three years of walking stripped and barefoot were a picture of what was coming: "So shall the king of Assyria lead away the Egyptians prisoners, and the Ethiopians captives, young and old, naked and barefoot." The mighty empires of the south, Egypt and Ethiopia, in whom the small nations put their hope, would themselves be marched off in the humiliating dress of prisoners of war. The point was aimed straight at any nation, Judah included, that was tempted to trade trust in God for an alliance with Egypt. The rescuer they were counting on would need rescuing.
Gospel Focus
This is God's standing warning against trusting the arm of flesh. Judah kept looking to Egypt's chariots and horses instead of to the LORD, and Isaiah's whole ministry pressed the same point: "Woe to them that go down to Egypt for help; and stay on horses, and trust in chariots... but they look not unto the Holy One of Israel" (Isaiah 31:1). Every age has its Egypt, some human power, wealth, or alliance we lean on in place of God. But the arm of flesh always fails at the last: "Cursed be the man that trusteth in man, and maketh flesh his arm... Blessed is the man that trusteth in the LORD, and whose hope the LORD is" (Jeremiah 17:5, 7). The nations that looked to Egypt found their hope led away in chains. Where are you looking for your rescue? If it is anywhere but God, it will one day be marched off barefoot before your eyes. Put your trust where it cannot be taken captive, in the Lord alone.
How Shall We Escape? (Isaiah 20:5-6)
Those who trusted in Egypt and Ethiopia are left afraid and ashamed, crying the desperate question of everyone whose refuge has failed.
Whither We Flee for Help
"And the inhabitant of this isle shall say in that day, Behold, such is our expectation, whither we flee for help to be delivered from the king of Assyria: and how shall we escape?"
Hebrew Study
The lesson lands on those who had pinned their hopes on Egypt: "they shall be afraid and ashamed of Ethiopia their expectation, and of Egypt their glory." When the power they trusted is dragged away in chains, their cry will be, "how shall we escape?" The point is pointed for Judah, tempted to trust political alliances instead of God: whoever leans on the arm of flesh will be put to shame when that arm is broken. The only safe "expectation" is the LORD Himself.
Explanation
When Egypt falls, those who trusted her are left "afraid and ashamed of Ethiopia their expectation, and of Egypt their glory." The "expectation" they had leaned on collapses, and the coastland peoples cry, "Behold, such is our expectation, whither we flee for help... and how shall we escape?" It is the voice of a people who suddenly see that the refuge they ran to cannot save them, and that the enemy is still coming. Their glory has become their shame, and their confidence has turned to terror.
Gospel Focus
"How shall we escape?" is the cry of every misplaced hope when the day of testing comes. Trust in the wrong refuge always ends the same way, in shame: "they shall be afraid and ashamed." But the opposite is also gloriously true. Those who trust in the Lord are never left ashamed: "Whosoever believeth on him shall not be ashamed" (Romans 10:11). The question "how shall we escape?" has only one true answer, and the New Testament makes it piercingly personal: "How shall we escape, if we neglect so great salvation?" (Hebrews 2:3). There is an escape, but it is not Egypt, not human strength, not any refuge of this world; it is the salvation God has provided in Jesus Christ. Do not wait until the day your false hopes are led away barefoot to discover they cannot save. Flee now to the one refuge that never fails, and you shall not be ashamed.
Chapter 20 in Review
Isaiah 20 is a short, vivid chapter built around a single prophetic sign. In the year Assyria took Ashdod, God commanded Isaiah to walk "naked and barefoot," stripped to the clothing of a captive, for three years. The sign had a plain meaning: so would Egypt and Ethiopia, the great powers the small nations were trusting for rescue, be led away by Assyria as prisoners, young and old, stripped and barefoot, to their shame. And those who had leaned on them would be left crying, "how shall we escape?"
For the Apostolic reader, the chapter presses two lessons. First, the cost of obedience: Isaiah "did so," bearing public humiliation for three years because God asked it, a reminder that His servants are sometimes called to obey in humbling, costly ways, as our Lord Himself was stripped and shamed for us. Second, and above all, the folly of trusting the arm of flesh: every Egypt we lean on in place of God will one day be marched off in chains. Misplaced hope ends in shame, but "whosoever believeth on him shall not be ashamed." The desperate question "how shall we escape?" has one answer, and it is not this world's help but the great salvation God has given in Christ. Flee to Him, and your refuge will never be led away.
- Isaiah's three years "naked and barefoot" were a costly sign-act; he simply "did so" (20:2-3).
- God's servants are sometimes called to humbling, costly obedience for the sake of the message (20:2).
- Egypt and Ethiopia, the nations trusted for rescue, would themselves be led away captive (20:4).
- Trusting the arm of flesh instead of God always ends in shame (20:5; Isaiah 31:1; Jeremiah 17:5, 7).
- "How shall we escape?" has one answer: the great salvation in Christ (20:6; Hebrews 2:3; Romans 10:11).
Questions for Reflection
- Is there a hard or humbling obedience God has asked of you that you have been resisting?
- What "Egypt" are you tempted to trust for rescue instead of God?
- Where are you fleeing for help, and will that refuge stand in the day of testing?

Scripture is quoted from the King James Version (KJV). The Hebrew terms are standard and can be checked in any Hebrew lexicon. Sargon II of Assyria and his capture of Ashdod (around 711 BC) are attested in Assyrian royal inscriptions, a striking confirmation of the historical marker in verse 1; "Tartan" is an Assyrian military title (commander-in-chief), not a personal name.
