What is the (or your) definition of unbled meat as described in 1 Samuel 14:32-35 where Saul fed his army unbled meat. I would assume that his army did not travel with a herd of sheep and the meat they ate would be from the wild.
I am a hunter and when I harvest a deer, I do not hang it and cut the throat. I have already dressed (disemboweled) the deer and that includes removing the heart from the inside which allows a total bloodletting.
There are Jdubs who hunt and it is quite obvious to game officials who they are because they will check in deer with the throat cut. Don't they know that cutting the throat of something already dead is useless? Ask any Medical Examiner and they will tell you the dead don't bleed.
