Isaiah 9:2

Thou hast multiplied the nation, Thou hast increased their joy; they joy before Thee according to the joy in harvest, as men rejoice when they divide the spoil.
The people walking in darkness have seen a great light; on those living in the land of the shadow of death, a light has dawned (note: Cited in Matthew 4:15–16).
