'Whether' 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;

that you may feast on the flesh of kings and the flesh of generals and the flesh of mighty men, on the flesh of horses and their riders, and on the flesh of all mankind, whether they are free men or slaves, great men or small."
