I remember something along not eating meat with blood still in it. Does it really mean that we cannot eat an animal when it's still alive or that blood is literally not okay?
Some too related follow up:
If it means that we can't eat living animals, can we eat cooked blood (a popular dishes in Indonesia).
Also, when eating meat, it's impossible to completely eliminate blood from the meat right. How do you deal with it?
But you must not eat meat that has its lifeblood still in it.
Does lifeblood here means life or blood? Indonesian translation translate that as simply blood I think followed with a strange theory that life is in the blood.
Satu-satunya yang tidak boleh kamu makan ialah daging yang masih ada darahnya, sebab nyawa itu ada di dalam darah.
Re-translated to English:
The only thing you cannot eat is meat that still has blood in it. That's because the soul is in the blood.
Other english translation:
Only, you shall not eat flesh with its life, that is, its blood.
Which suggest that Indonesian translation is not that far off.
http://bible.cc/deuteronomy/12-23.htm suggest that it could be the same "Genesis" law that mimic the indonesian translation. Don't eat blood, followed by a theory that life is in the blood.
