The Union forever, Hurrah! boys, hurrah! Down with the traitors, Up with the stars; While we rally round the flag, boys, Rally once again, Shouting the battle cry of Freedom!
. . . . it is not right that any man should be in bondage one to another.
And for this purpose have I established the Constitution of this land. . . . D&C 101:79-80
Verily, thus saith the Lord concerning the wars that will shortly come to pass, beginning at the rebellion of South Carolina, which will eventually terminate in the death and misery of many souls . . . . the Southern States shall be divided against the Northern States, and the Southern States will call on other nations, even the nation of Great Britain. . . . after many days, slaves shall rise up against their masters, who shall be marshaled and disciplined for war. D&C 87:1-4 (1832).
[Note the word rebellion. And it might be better to say former slaves, but it is from the perspective of prophesying the future, so current and future context are not always easy to explain or interpret. Just ask Marty McFly or Dr. Who.]Ring out, wild bells!
