Isaiah 42:12 calls on people to honor the LORD and to speak of His praise, and it reaches even to distant coastlands and islands. The verse is a summons to glorify God openly, not only in the homeland of Israel but among every people who live far from it. The words come from the prophet Isaiah, who speaks on behalf of God to a community of exiles and to a wider world that needs to hear who the LORD really is.
Let them give glory to the LORD, and declare his praise in the islands.

What Isaiah 42:12 Means
The verse begins with an invitation: “Let them give glory to the LORD.” To give glory means to recognize God’s greatness and to make it visible through how we speak, sing and live. It is not something God needs in order to be God. It is the response that fits who He is, and the verse describes it as something that should happen freely and joyfully.
The second half widens the circle: “declare his praise in the islands.” The word “islands” in Isaiah often means faraway lands beyond the familiar world of Israel, the coastlands of the Mediterranean and beyond. The prophet pictures news of God’s faithfulness travelling to places that have never heard of Him, and asks the people who know Him to carry that news outward.
What the verse does not do is give a formula for how that praise will be received or what results will follow. It describes a calling and a hope. The promise underneath it is that the LORD’s reputation will reach people who have not yet known Him, and the reader is invited to be part of that spreading testimony.
The Context of Isaiah 42:12
The book of Isaiah is traditionally attributed to the prophet Isaiah, who ministered in Jerusalem in the eighth century before Christ. Chapters 40 through 55 are often called Second Isaiah, and many scholars date this section to the time of the Babylonian exile, when many of God’s people were far from home and wondering whether the LORD had forgotten them. The audience is those exiles and, through them, the wider world.
The verses just before this one, Isaiah 42:9 through 11, announce new things that God is about to do and call for a “new song” from the farthest ends of the earth. Verses 13 through 15 then describe the LORD going out like a warrior to triumph over His enemies. Read in that setting, verse 12 is part of a burst of worship that moves from the mouths of God’s people outward to the whole earth, and it shows that God’s victory is cause for praise far beyond Israel’s borders.

A Short Prayer From Isaiah 42:12
Lord, You are worthy of all glory, and I want my life to make that plain. Give me words to speak of Your goodness, both to those close to me and to people far beyond my reach. Let my praise be honest and steady, even when I feel quiet or unsure. Send Your truth to every shore and every heart that has not heard it yet, and use me in whatever small way You choose. Amen.
