John 6:61-71

61But Jesus, 1aware that His disciples were complaining about this, said to them, “Is this 23offensive to you? 62What then if you see 4the Son of Man 5ascending to where He was before? 636It is the Spirit who gives life; the flesh provides no benefit; 7the words that I have spoken to you are spirit, and are life. 64But there are 8some of you who do not believe.” For Jesus 9knew from the beginning who they were who did not believe, and 10who it was who would 11betray Him. 65And He was saying, “For this reason I have 12told you that no one can come to Me unless 13it has been granted him from the Father.”

66As a result of this many of His 14disciples 15left, and would no longer walk with Him. 67So Jesus said to 16the twelve, “You do not want to leave also, do you?” 6817Simon Peter answered Him, “Lord, to whom shall we go? You have 18words of eternal life. 69And we have already believed and have come to know that You are 19the Holy One of God.” 70Jesus answered them, “20Did I Myself not choose you, 21the twelve? And yet one of you is 22a devil.” 71Now He meant Judas 23the son of Simon Iscariot; for he, 24one of 25the twelve, 26was going to betray Him.
