Isaiah 60:19-22
The Lord Himself becomes Zion’s everlasting light.
19 The sun will be no more your light by day; nor will the brightness of the moon give light to you, but Yahweh will be your everlasting light, and your God will be your glory.
20 Your sun will not go down any more, nor will your moon withdraw itself; for Yahweh will be your everlasting light, and the days of your mourning will end.
21 Then your people will all be righteous. They will inherit the land forever, the branch of my planting, the work of my hands, that I may be glorified.
22 The little one will become a thousand, and the small one a strong nation. I, Yahweh, will do this quickly in its time.”
The LORD himself becomes Zion’s everlasting light.
To describe the climactic glory of Zion where the LORD himself is everlasting light and righteousness secures permanent peace.
In contrast to present suffering and instability, the promise envisions a future state of permanent light, joy, and divine presence.
Zion Arises as the LORD’s Glory Draws the Nations
Because the LORD’s glory rises upon Zion, darkness gives way to light, scattered children return, nations bring tribute, former shame is reversed, peace and righteousness govern, and the LORD himself becomes everlasting light.
