They drank it often in their sacrificial feasts and in making covenants. Thus this rules out blood pudding. Rare steaks have most of the blood removed prior to eating. Animals strangled and which have not been properly bled when butchered should not be used for food likewise. Now, it takes a wild stretch of one's imagination to conclude from the stated Scriptures that one is to avoid receiving a blood transfusion in order to restore life or to even save a life.
Some today are fearful of contacting a virus or disease from donated blood from a blood bank.
Therefore, they have the privilege of donating their own blood in preparation for a surgery, if it is needed. What a wonderful day in which we live when blood transfusions, and organ transplants are available to assist us medically. May we be very thankful to our God who gives the medical profession the knowledge they need to assist us. May we also thank our God for giving us a brain with which to reason and not follow man made false doctrines such as the refusal of a blood transfusion.
