The Great Light. Isaiah 9: 2-4

The people walking in darkness have seen a great light; on those living in the land of deep darkness a light has dawned.
You have enlarged the nation and increased their joy; they rejoice before you as people rejoice at the harvest, as warriors rejoice when dividing the plunder.
For as in the day of Midian’s defeat, you have shattered the yoke that burdens them, the bar across their shoulders, the rod of their oppressor.
Isaiah 9: 2-4
