Judaism and Christianity have always understood these scriptures to ban blood-eating for nourishment. This underlies Judaism's kosher procedures to extract blood from meat, which Witnesses do not follow. Christianity eventually decided the rule was temporary.
Nah...
The Noahide Laws (Laws of the sons of Noah given by God to gentiles after the flood and as binding as the decalogue was to Jews) mention this selfsame
prohibition and it has nothing to do with eating blood for nourishment. It has to do with SHEDDING blood in revenge (atonement murder which is still practiced in half the world by next of kin.)
Not eating things strangled is the clause that covers eating blood for nourishment.
