'My Blood' in the Bible

"You must all drink from it, for this is my blood which ratifies the agreement, and is to be poured out for many people, for the forgiveness of their sins.

And he said to them, "This is my blood which ratifies the agreement, and is to be poured out for many people.

Whoever lives on my flesh and drinks my blood possesses eternal life, and I will raise him to life on the Last Day.

For my flesh is real food and my blood is real drink.

Whoever lives on my flesh and drinks my blood remains united to me and I remain united to him.

He took the cup, too, after supper, in the same way, saying, "This cup is the new agreement ratified by my blood. Whenever you drink it, do so in memory of me."
