Isaiah 27:13 promises that a day is coming when God will call his scattered people home, including those exiled far away in Assyria and Egypt, and they will return to worship him in Jerusalem. The verse looks forward to a future gathering that God himself will bring about. The prophet Isaiah spoke these words to the people of Judah, who lived under the shadow of foreign empires and knew what it meant to be far from the place of God’s presence.
It will happen in that day that a great trumpet will be blown; and those who were ready to perish in the land of Assyria, and those who were outcasts in the land of Egypt, shall come; and they will worship the LORD in the holy mountain at Jerusalem.

What Isaiah 27:13 Means
The verse opens with “in that day,” a phrase Isaiah uses often to point to a time when God acts decisively in history. The sound of a great trumpet was a signal in ancient Israel, used to call people together, to announce a royal event, or to summon an army. Here the trumpet calls the scattered back, much like a shepherd’s call draws the flock from the hills.
The people described are those “ready to perish” in Assyria and “outcasts” in Egypt. These are not just distant travelers. They are the exiled and the forgotten, people who had lost their land, their homes, and often their sense of belonging. The verse says they will come, and their coming ends with worship of the LORD on his holy mountain at Jerusalem.
What the verse does not do is spell out every detail of how or when this happens. It describes the outcome with confidence, but it leaves the timing and manner in God’s hands. It promises a restored people, not a formula for daily comfort, and it places the hope in the character of the One who calls.
The Context of Isaiah 27:13
The book of Isaiah is traditionally attributed to the eighth-century prophet of that name, who ministered in Jerusalem during a time of political upheaval. Chapters 24 through 27 are often called the “Isaiah Apocalypse” because they describe judgment and restoration on a broad scale. Chapter 27 moves from judgment on the fortified city toward a promise that God will gather his people one by one.
Just before verse 13, verse 12 speaks of God threshing from the Euphrates to the brook of Egypt and gathering the children of Israel one at a time. Verse 13 then names the two places of exile most associated with Israel’s history. Read in that setting, the trumpet call is the announcement of a gathering that reverses the scattering, and the worship at Jerusalem becomes the goal of the whole movement.

Ezekiel speaks of God taking the people of Israel from among the nations where they have been scattered and bringing them back to their own land. Like Isaiah 27:13, it describes a gathering that God himself initiates, reversing the dispersion of exile.
Jeremiah 29:14
I will be found by you,” says the LORD, “and I will turn again your captivity, and I will gather you from all the nations, and from all the places where I have driven you, says the LORD. I will bring you again to the place from where I caused you to be carried away captive.”

Jeremiah assures the exiles in Babylon that God will be found by them and will gather them from every place where he has driven them. It echoes the same promise of return and shows that the gathering is rooted in God’s own faithfulness to his people.
A Short Prayer From Isaiah 27:13
Lord, you know the places where I feel far from you and the people I have lost touch with. Some days I wonder whether you still see me in the distance. Thank you that your promise is not limited by how far I have wandered. Gather me back to yourself, and gather the people I love who feel scattered. Let me worship you in the place where you meet your people, and let that worship be my home. Amen.
