'Loins' in the Bible

girded with belts on their loins, with flowing turbans on their heads, all of them looking like officers, like the Babylonian men whose native land was Chaldea.

They shall have linen turbans on their heads and linen undergarments on their loins; they shall not dress themselves with anything which makes them sweat.

Again he measured a thousand [cubits] and led me through the water, water that was knee-deep. Again he measured a thousand [cubits] and led me through the water, water reaching the hips.
