What does “campground” refer to in the spiritual “Deep River”?

“Deep River,” like “My God Is a Rock,” belongs in the category of slow, quiet spirituals. These songs of despair and hope were sometimes forbidden by slaveowners or overseers, while more up-tempo songs were actively encouraged as being helpful to keep the work going.
Why do the words say, “I want to cross over into campground”? I’ve noticed before that “campground” doesn’t really fit the rhythm very well. And for me, the image conjured up is that of tents, campfires, and lots of children running around. Almost like a refugee camp. (The fact that I have promised myself that I will never, ever again sleep on the ground in a tent might color my perceptions a bit.) Someone else might think of Civil War soldiers’ camps. Why would persecuted people want to escape to something so . . . unrestful?
