John 6:52

49 your fathers did eat the manna in the wilderness, and they died;

50 this is the bread that out of the heaven is coming down, that any one may eat of it, and not die.

51 `I am the living bread that came down out of the heaven; if any one may eat of this bread he shall live -- to the age; and the bread also that I will give is my flesh, that I will give for the life of the world.`

52 The Jews, therefore, were striving with one another, saying, `How is this one able to give us [his] flesh to eat?`

53 Jesus, therefore, said to them, `Verily, verily, I say to you, If ye may not eat the flesh of the Son of Man, and may not drink his blood, ye have no life in yourselves;

54 he who is eating my flesh, and is drinking my blood, hath life age-during, and I will raise him up in the last day;

55 for my flesh truly is food, and my blood truly is drink;
