John 6:53-55

Young's Literal Translation

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;
