64 It is the spirit that quickeneth: the flesh profiteth nothing. The words that I have spoken to you, are spirit and life.
65 But there are some of you that believe not. For Jesus knew from the beginning, who they were that did not believe, and who he was, that would betray him.
66 And he said: Therefore did I say to you, that no man can come to me, unless it be given him by my Father.
67 After this many of his disciples went back; and walked no more with him.
68 Then Jesus said to the twelve: Will you also go away?
69 And Simon Peter answered him: Lord, to whom shall we go? thou hast the words of eternal life.
