John 6:64 DBY

⁶²  If then ye see the Son of man ascending up where he was before?

⁶³  It is the Spirit which quickens, the flesh profits nothing: the words which I have spoken unto you are spirit and 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 would deliver him up.

⁶⁵  And he said, Therefore said I unto you, that no one can come to me unless it be given to him from the Father.

⁶⁶  From that [time] many of his disciples went away back and walked no more with him.
