After the Flood, the fear and dread of humanity fell upon the animals, fowls, and fish (Geneses 9:1-4). Evidently this condition did not exist between humans and other creatures prior to this time. Simultaneously, God specifically allowed humans to eat anything they wanted for food. “Every moving thing that liveth shale meat for you” (Genesis 9:3). He places only one restriction concerning what they ate: “But flesh with the life thereof, which is the blood thereof, shall ye not eat” (Genesis 9:4). Clearly stated, He prohibited humans from eating blood. They were to drain the blood from animals before eating them, and they were not to eat blood after they drained it from the animal.
God’s rule regarding humanity’s diet was in effect for many years with no changes or alterations. Moses’ law brought significant changes to what the Israelites were to eat.
