John 6:64-66

Revised Standard Version Catholic Edition

⁶⁴ But there are some of you that do not believe.” For Jesus knew from the first who those were that did not believe, and who it was that should betray him. ⁶⁵ And he said, “This is why I told you that no one can come to me unless it is granted him by the Father.”

⁶⁶ After this many of his disciples drew back and no longer went about with him.
