John 6:60-71 - Many Disciples Desert Jesus
60 Many therefore of his disciples, who heard him, said, Difficult is this discourse, who is able to fathom it?
61 Then Jesus, conscious in himself that his disciples murmured concerning this discourse, said unto them, Doth this stumble you? 62 What then if ye see the Son of man ascending where he was formerly? 63 The Spirit is the life-giving power; the flesh contributeth nothing: the declarations which I make to you, they are spirit, and they are life. 64 But there are some of you who do not believe. For Jesus knew from the beginning who they were who did not believe, and who the person was that should betray him. 65 And he said, Therefore have I informed you, That no man can come to me, except it be given him of my Father.
66 From that [discourse] many of his disciples went away back, and no more followed him about. 67 Then said Jesus to the twelve, Will ye also go away?
68 Then Simon Peter answered him, Lord, unto whom shall we go from thee? thou hast the words of eternal life. 69 And we have believed and known that thou art the Messiah, the Son of the living God.
70 Jesus answered them, Have I not chosen you twelve, and one of you is a devil? 71 Now he spake of Judas Iscariot, the son of Simon: for this man was ready to betray him, though he was one of the twelve.
