John 6:60-71

⁶⁰Therefore many of His disciples, when they heard this said, “This is a difficult statement; who can listen to it?” ⁶¹But Jesus, conscious that His disciples grumbled at this, said to them, “Does this cause you to stumble? ⁶²What then if you see the Son of Man ascending to where He was before? ⁶³It is the Spirit who gives life; the flesh profits nothing; the words that I have spoken to you are spirit and are life. ⁶⁴But there are some of you who do not believe.” For Jesus knew from the beginning who they were who did not believe, and who it was that would betray Him. ⁶⁵And He was saying, “For this reason I have said to you, that no one can come to Me unless it has been granted him from the Father.”

⁶⁶As a result of this many of His disciples withdrew and were not walking with Him anymore. ⁶⁷So Jesus said to the twelve, “You do not want to go away also, do you?” ⁶⁸Simon Peter answered Him, “Lord, to whom shall we go? You have words of eternal life. ⁶⁹We have believed and have come to know that You are the Holy One of God.” ⁷⁰Jesus answered them, “Did I Myself not choose you, the twelve, and yet one of you is a devil?” ⁷¹Now He meant Judas the son of Simon Iscariot, for he, one of the twelve, was going to betray Him.
