About 2,400 years before our Common Era, he entrusted Noah with the revelation that human life and blood are sacred​—a truth that would be of prime importance when the promised Seed arrived.​—Genesis 9:1-7.

Jesus was also Jehovah’s appointed High Priest, who gave his untainted, perfect life as a ransom for mankind​—a most marvelous application of the principle of the sacredness of blood. (Hebrews 7:26; 9:26)
