Isaiah 20

1
In the year that Tartan came to Ashdod, when Sargon the king of Assyria sent him, and he fought against Ashdod and took it;
2
at that time the LORD spoke by Isaiah the son of Amoz, saying, “Go, and loosen the sackcloth from off your waist, and take your sandals from off your feet.” He did so, walking naked and barefoot.
3
The LORD said, “As my servant Isaiah has walked naked and barefoot three years for a sign and a wonder concerning Egypt and concerning Ethiopia,
4
so the king of Assyria will lead away the captives of Egypt and the exiles of Ethiopia, young and old, naked and barefoot, and with buttocks uncovered, to the shame of Egypt.
5
They will be dismayed and confounded, because of Ethiopia their expectation, and of Egypt their glory.
6
The inhabitants of this coast land will say in that day, ‘Behold, this is our expectation, where we fled for help to be delivered from the king of Assyria. And we, how will we escape?’”

Overview.
This chapter records a prophetic sign-act performed by Isaiah at the Lord’s command: walking naked and barefoot for three years as a symbol of the coming humiliation of Egypt and Ethiopia when conquered by Assyria. The act serves not only as a warning against reliance on foreign powers but also as a demonstration of God’s sovereign control over nations, using Israel’s prophets and events in the ancient Near East to convey divine judgment and the futility of human alliances.

Flow.

  • The chapter opens with historical context: the Assyrian military campaign against Ashdod under Tartan, Sargon’s commander.
  • The LORD instructs Isaiah to remove his sackcloth and sandals, walking naked and barefoot as a symbolic act.
  • The meaning is explained: this sign enacts the future captivity and shame of Egypt and Ethiopia, stripped and led away by Assyria.
  • The coastal peoples, who had hoped in Egypt and Ethiopia for deliverance from Assyria, are left in dismay, realizing their helpless state.

Connections.
Following chapter 19, which details the downfall of Egypt and the Lord’s purposes in judging and ultimately restoring her, chapter 20 reinforces the theme of Egypt’s weakness and the vanity of trusting in her for deliverance. The symbolic action of Isaiah underscores the certainty of divine pronouncements already declared. It serves as a hinge between the focus on Egypt’s fate and the broader warnings to Judah about foreign alliances that chapter 21 will continue to unfold, particularly in the context of geopolitical instability and the rise of empires. The message of human helplessness before God’s decree prepares Judah—and the reader—for the deepening emphasis on trust in the Lord alone that will emerge in later chapters.

What it teaches.
The chapter reveals God’s sovereign direction of history, using the actions of prophets and the rise and fall of nations to make known His judgments. It warns against placing confidence in human strength or political alliances rather than in the Lord, who alone controls the destinies of kingdoms (WCF 5.6). The exposure and shame of conquered nations reflect the seriousness of pride and misplaced trust, teaching that deliverance belongs to the LORD alone (HC LD 1). The prophetic sign-act also illustrates how God condescends to human understanding, using visible, embodied messages to confirm His word (WCF 1.1, LC 2).

Apply.
Trust in political or military alliances is no substitute for reliance on God’s promised deliverance.
