Albert Barnes Commentary Isaiah 60:3

"And nations shall come to thy light, and kings to the brightness of thy rising." — Isaiah 60:3 (ASV)

And the Gentiles shall come - So splendid shall be that glory, that it will attract the distant nations, and they shall come and participate in the blessings of the gospel. This contains the main statement that this chapter is designed to illustrate. The prophet had frequently made this statement before in general terms (Isaiah 11:10; Isaiah 49:22; Isaiah 54:3); but he now goes into a more particular account, and more fully describes the blessings that would result from this accession to the true church.

And kings - (Compare Isaiah 49:7, note; Isaiah 49:23, note; Isaiah 52:15, note).

To the brightness of thy rising - This does not mean that the church was to arise with the splendor of the sun; but thy rising means the rising upon her - called her rising, because it would shed its beams on her. It is correctly rendered by Lowth - ‘The brightness of your sunrising;’ and by Noyes and Herder - ‘The brightness that rises upon you.’
