'Blood' in the Bible

who have been born, not of blood, nor of flesh's will, nor of man's will, but of God.

Jesus therefore said to them, Verily, verily, I say unto you, Unless ye shall have eaten the flesh of the Son of man, and drunk his blood, ye have no life in yourselves.

He that eats my flesh and drinks my blood has life eternal, and I will raise him up at the last day:

for my flesh is truly food and my blood is truly drink.

He that eats my flesh and drinks my blood dwells in me and I in him.

but one of the soldiers pierced his side with a spear, and immediately there came out blood and water.
