'Slave' in the Bible

Then the kings of the earth and the great men and the military commanders and the wealthy and the strong and everyone, [whether] slave or free, hid themselves in the caves and among the rocks of the mountains;

Also he compels all, the small and the great, and the rich and the poor, and the free men and the slaves, to be given a mark on their right hand or on their forehead [signifying allegiance to the beast],

so that you may feast on the flesh of kings, the flesh of commanders, the flesh of powerful and mighty men, the flesh of horses and of those who sit on them, and the flesh of all humanity, both free men and slaves, both small and great [in a complete conquest of evil].”
