John 6:54 YLT

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;

⁵⁶  he who is eating my flesh, and is drinking my blood, doth remain in me, and I in him.
