John 6:65 WBT

⁶³  It is the spirit that reviveth; the flesh profiteth nothing: the words that I speak to you, [they] are spirit, and [they] are life.

⁶⁴  But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who he was that would betray him.

⁶⁵  And he said, Therefore I said to you, that no man can come to me, except it were given to him by my Father.

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

⁶⁷  Then said Jesus to the twelve, Will ye also go away?
