1 Corinthians 10:16King James Version (KJV)
16 The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?
1 Corinthians 11:23-30King James Version (KJV)
23 For I have received of the Lord that which also I delivered unto you, that the Lord Jesus the same night in which he was betrayed took bread:
24 And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me.
25 After the same manner also he took the cup, when he had supped, saying, this cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me.
26 For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
27 Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.
28 But let a man examine himself, and so let him eat of that bread, and drink of that cup.
29 For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
30 For this cause many are weak and sickly among you, and many sleep.
Matthew 26:17-30King James Version (KJV)
17 Now the first day of the feast of unleavened bread the disciples came to Jesus, saying unto him, Where wilt thou that we prepare for thee to eat the passover?
18 And he said, Go into the city to such a man, and say unto him, The Master saith, My time is at hand; I will keep the passover at thy house with my disciples.
19 And the disciples did as Jesus had appointed them; and they made ready the passover.
20 Now when the even was come, he sat down with the twelve.
21 And as they did eat, he said, Verily I say unto you, that one of you shall betray me.
22 And they were exceeding sorrowful, and began every one of them to say unto him, Lord, is it I?
23 And he answered and said, He that dippeth his hand with me in the dish, the same shall betray me.
24 The Son of man goeth as it is written of him: but woe unto that man by whom the Son of man is betrayed! it had been good for that man if he had not been born.
25 Then Judas, which betrayed him, answered and said, Master, is it I? He said unto him, Thou hast said.
26 And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body.
27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it;
28 For this is my blood of the new testament, which is shed for many for the remission of sins.
29 But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father's kingdom.
30 And when they had sung an hymn, they went out into the mount of Olives.
Revelation 3:20King James Version (KJV)
20 Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
John 6:48-63King James Version (KJV)
48 I am that bread of life.
49 Your fathers did eat manna in the wilderness, and are dead.
50 This is the bread which cometh down from heaven, that a man may eat thereof, and not die.
51 I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world.
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.
60 Many therefore of his disciples, when they had heard this, said, This is an hard saying; who can hear it?
61 When Jesus knew in himself that his disciples murmured at it, he said unto them, Doth this offend you?
62 What and if ye shall see the Son of man ascend up where he was before?
63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
John 13:1-17King James Version (KJV)
13 Now before the feast of the passover, when Jesus knew that his hour was come that he should depart out of this world unto the Father, having loved his own which were in the world, he loved them unto the end.
2 And supper being ended, the devil having now put into the heart of Judas Iscariot, Simon's son, to betray him;
3 Jesus knowing that the Father had given all things into his hands, and that he was come from God, and went to God;
4 He riseth from supper, and laid aside his garments; and took a towel, and girded himself.
5 After that he poureth water into a bason, and began to wash the disciples' feet, and to wipe them with the towel wherewith he was girded.
6 Then cometh he to Simon Peter: and Peter saith unto him, Lord, dost thou wash my feet?
7 Jesus answered and said unto him, What I do thou knowest not now; but thou shalt know hereafter.
8 Peter saith unto him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me.
9 Simon Peter saith unto him, Lord, not my feet only, but also my hands and my head.
10 Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all.
11 For he knew who should betray him; therefore said he, Ye are not all clean.
12 So after he had washed their feet, and had taken his garments, and was set down again, he said unto them, Know ye what I have done to you?
13 Ye call me Master and Lord: and ye say well; for so I am.
14 If I then, your Lord and Master, have washed your feet; ye also ought to wash one another's feet.
15 For I have given you an example, that ye should do as I have done to you.
16 Verily, verily, I say unto you, The servant is not greater than his lord; neither he that is sent greater than he that sent him.
17 If ye know these things, happy are ye if ye do them.
