Isa 62:1-12. Intercessory Prayers for Zion's Restoration, Accompanying God's Promises of It, as the Appointed Means of Accomplishing It.
1. I—the prophet, as representative of all the praying people of God who love and intercede for Zion (compare Isa 62:6, 7; Ps 102:13-17), or else Messiah (compare Isa 62:6). So Messiah is represented as unfainting in His efforts for His people (Isa 42:4; 50:7).
righteousness thereof—not its own inherently, but imputed to it, for its restoration to God's favor: hence "salvation" answers to it in the parallelism. "Judah" is to be "saved" through "the Lord our (Judah's and the Church's) righteousness" (Jer 23:6).
as brightness—properly the bright shining of the rising sun (Isa 60:19; 4:5; 2Sa 23:4; Pr 4:18).
lamp—blazing torch.
