Isaiah Chapter 20: Walk of Faith

Study Isaiah 20 verse by verse and explore Isaiah's unusual three-year walk, a living sign that called Judah to trust the Lord for deliverance when everything around them looked dark.

Isaiah 20 shows a prophet obeying an odd command and warns against trusting any nation instead of God.

Chapter overview

Walk of Faith

In our study of Isaiah Chapter 20, we look at Isaiah's unusual walk to call Judah to trust in the Lord for deliverance. At a time when things around them were looking very dark, the prophet urged the people to trust in God.

The chapter begins in the year Sargon's commander captured Ashdod. Up to this point, Isaiah had spoken to Judah's leaders with words. Now God tells him to remove his sackcloth and sandals and walk around barefoot and unclothed for three years as a sign of what would happen to Egypt and Cush at the hands of Assyria. The nations Judah was tempted to lean on would be led away in shame, and the people who trusted in them would ask, "How will we escape now?"

  • God tells Isaiah to obey an unusual command as a public sign.
  • Egypt and Cush, the hope of many in the region, fall to Assyria in shame.
  • The only safe path is a walk of faith that begins by trusting the Deliverer.

Isaiah Chapter 20 Verse-by-Verse Commentary

Isaiah 20:1

In the year that Sargon the king of Ashur sent his commander-in-chief to attack Ashdod, he captured it.

We begin with the establishment of the time that we are talking about. Sargon, king of Assyria, is Sargon II, who reigned over Assyria from 721 to 705 B.C. Ashdod was located in Samaria on the Mediterranean coast and, at this time, it was a Philistine city. During this time, the Assyrians had invaded the northern kingdom (Israel) and captured it.

Isaiah 20:2

It was at that time that ADONAI, speaking through Yesha'yahu the son of Amotz, said, "Go and unwind the sackcloth from around your waist, and take your sandals off your feet." So he did it, going about unclothed and barefoot.

Up to this point, God had used Isaiah to communicate with the leaders of Judah with words calling them to repentance. Now, the prophet is told to remove his clothes and walk around Judah naked and barefoot as a sign of judgment that is to come. Being barefoot was a sign of severe poverty, while being naked was a sign of shame. This probably strikes all of us as an unusual request, just as it probably did with Isaiah. Nevertheless, the prophet did as he was told. This is a good lesson for us as well in the fact that we must trust in the fact that God knows all and has a plan for each and every one of us. At first, it may seem odd, but we all have our own walk of faith.

Isaiah 20:3–4

In time, ADONAI said, "Just as my servant Yesha'yahu has gone about unclothed and barefoot for three years as a sign and portent against Egypt and Ethiopia, so will the king of Ashur lead away the captives of Egypt and the exiles of Ethiopia, young and old, unclothed and barefoot, with their buttocks exposed, to the shame of Egypt.

We see that Isaiah walked around this way for three years. We are reminded that, throughout the Bible, the number three is associated with the earthly display of God's will. The purpose of Isaiah's walk of faith was to be an example of what would happen to the Egyptians and Cushites at the hands of the Assyrians.

Isaiah 20:5

They will be dismayed and ashamed because of Ethiopia their hope and Egypt their pride.

The northern kingdom of Israel had joined with Egypt in the battle against the Assyrians. They all tried to get the king of Judah to join the alliance. Isaiah was warning them that they should not trust in any nation to protect them but instead should trust in God. The same thing holds true for us, as Christians, and for the land of Israel today. Yeshua is our deliverer, and we must always remember that. In Revelation, we are told of the day when a rider will come on a white horse (see Revelation 6). This rider will bring a supposed peace to a troubled world, but it is a false peace, just as the northern kingdom had falsely trusted in Egypt and Cush to help them.

Isaiah 20:6

On that day, the people living along this coast will say, 'Look what happened to the people to whom we fled for help, hoping they would rescue us from the king of Ashur! How will we escape now?'"

When the people that they had trusted in are led away in shame, the people will lose hope. It is the same with those who will trust in an earthly leader in the last days. At the mid-point of a peace treaty, they will realize that it was a false hope, and the world will find itself enslaved. The only way to avoid this is to trust in our Deliverer and His provision for our peace with God. We all have a walk of faith that is set before us, and each walk begins with a first step. That first step is accepting Yeshua as our Deliverer.

Messianic Themes in Isaiah Chapter 20

Messianic Themes

The One Who Bore Our Shame

Isaiah was told to walk stripped and barefoot as a sign of the shame that judgment would bring. The prophet's own name means "ADONAI saves," and it comes from the same root as the name Yeshua. Centuries later, Yeshua was stripped of His garments and hung in public view (Matthew 27:28, 35), enduring the cross and despising its shame (Hebrews 12:2), so that those who trust in Him would not be put to shame (Romans 10:11).

The Deliverer From Zion

Judah was tempted to trust in Egypt and Cush, but Isaiah pointed them to God alone. Psalm 118:8–9 says it is better to take refuge in ADONAI than to trust in people or princes, and Romans 11:26 declares that the Deliverer will come from Zion.

A Walk Begun With One Step

Isaiah's obedience to an unusual command shows that faith is something we walk out. Yeshua invites His followers to take up their cross and follow Him (Matthew 16:24), and Sha'ul writes that we walk by faith, not by sight (2 Corinthians 5:7).

Did You Know?

A Sign Lived Out for Three Years

Isaiah did not deliver this message once. He walked barefoot and unclothed for three years as a public sign against Egypt and Cush. The commentary notes that the number three is often associated in Scripture with the earthly display of God's will.

Key Takeaway

Every Walk of Faith Begins With a First Step

Isaiah trusted that God knew what He was doing, even when the command seemed odd. For every believer, the first step of the walk is accepting Yeshua as Deliverer, and Proverbs 3:5–6 promises that God will direct the paths of those who trust in Him with all their heart.

Questions for Reflection

Read through these questions after completing Isaiah Chapter 20 on your own or with a group.

  1. Isaiah obeyed a command that must have felt embarrassing and strange. Is there something God has asked of you that seems odd or uncomfortable, and what has kept you from taking that step?
  2. The people in this chapter placed their hope in Egypt and Cush and were left asking, "How will we escape now?" Where do you look first when you need rescue, and does that source last?
  3. Isaiah's message was lived out over three years, not spoken once. How can your daily life, and not only your words, point people toward trust in God?
  4. The commentary says every walk of faith begins with a first step. Where are you on that walk, and what would your next step of trust look like this week?
