Jubilee

Right there in the middle of the movie Glory is a great biblical reference.

That's right, Hines. Ain't no dream. We runaway slaves but we come back fightin' men. Go tell your folks how kingdom come in the year of jubilee!

In the Old Testament, year of jubilee was a year of liberation: of servants, property, the land, debts and crops. All property sold as payment to relieve poverty, was to be returned to the original owners without restoration of the original amount advanced. The Old Testament describes the land as God's inheritance, given to all Israel
The land cannot be sold permanently because the land is mine and you are foreigners—you're my tenants. You must provide for the right of redemption for any of the land that you own. Leviticus 25); See also Ezekiel 33
In the New Testament, Jesus extends the jubilee by proclaiming a year of good news to the poor, release for captives, sight to the blind, and liberation to the oppressed. He taught his disciples to pray for the forgiveness of debts (as we forgive our debtors). Pentecost was characterized by the voluntary sharing of possessions, so that there was not a needy person among them. Acts 3:34, cf. Deuteronomy 15:40
Christian disciples of the American South understood freedom in this way. Freedom granted by God as an establishment of His kingdom. Freedom has always been a key element in the Kingdom of God. Christian men and women are free to serve because they are holy and set apart; they are not bound to the kingdom of this world. They are bound together, spiritually and courageously, to the One who has granted their freedom.

Good morning gentlemen, I am Colonel Robert Gould Shaw. I am your commanding officer. It is a great pleasure to see you all here today. It is my hope that the same courage, spirit, and honor, which has brought us together, will one day restore this Union. May God bless us all.
