John 6:64-66

American Standard Version

⁶⁴ But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who it was that should ^[a]betray him. ⁶⁵ And he said, For this cause have I said unto you, that no man can come unto me, except it be given unto him of the Father.

⁶⁶ Upon this many of his disciples went back, and walked no more with him.
