John 6:52-59 King James Version (KJV)
52 The Jews therefore strove among themselves, saying, How can this man give us his flesh to eat?
53 Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you.
54 Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day.
55 For my flesh is meat indeed, and my blood is drink indeed.
56 He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him.
57 As the living Father hath sent me, and I live by the Father: so he that eateth me, even he shall live by me.
58 This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever.
59 These things said he in the synagogue, as he taught in Capernaum.
John 6:52-59 Amplified Bible, Classic Edition (AMPC)
52 Then the Jews angrily contended with one another, saying, How is He able to give us His flesh to eat?
53 And Jesus said to them, I assure you, most solemnly I tell you, you cannot have any life in you unless you eat the flesh of the Son of Man and drink His blood [unless you appropriate His life and the saving merit of His blood].
54 He who feeds on My flesh and drinks My blood has (possesses now) eternal life, and I will raise him up [from the dead] on the last day.
55 For My flesh is true and genuine food, and My blood is true and genuine drink.
56 He who feeds on My flesh and drinks My blood dwells continually in Me, and I [in like manner dwell continually] in him.
57 Just as the living Father sent Me and I live by (through, because of) the Father, even so whoever continues to feed on Me [whoever takes Me for his food and is nourished by Me] shall [in his turn] live through and because of Me.
58 This is the Bread that came down from heaven. It is not like the manna which our forefathers ate, and yet died; he who takes this Bread for his food shall live forever.
59 He said these things in a synagogue while He was teaching at Capernaum.
John 6:52-59 Living Bible (TLB)
52 Then the Jews began arguing with each other about what he meant. “How can this man give us his flesh to eat?” they asked.
53 So Jesus said it again, “With all the earnestness I possess I tell you this: Unless you eat the flesh of the Messiah* and drink his blood, you cannot have eternal life within you. 54 But anyone who does eat my flesh and drink my blood has eternal life, and I will raise him at the Last Day. 55 For my flesh is the true food, and my blood is the true drink. 56 Everyone who eats my flesh and drinks my blood is in me, and I in him. 57 I live by the power of the living Father who sent me, and in the same way those who partake of me shall live because of me! 58 I am the true Bread from heaven; and anyone who eats this Bread shall live forever, and not die as your fathers did—though they ate bread from heaven.” 59 (He preached this sermon in the synagogue in Capernaum.)
