“Jesus answered them: Have not I chosen you twelve; and one of you is a devil? Now he meant Judas Iscariot, the son of Simon: for this same was about to betray him whereas he was one of the twelve” (John 6:71-2).
Then went one of the twelve, who was called Judas Iscariot, to the chief priests, and said to them: What will you give me, and I will deliver him unto you? (Matthew 26:14-5)
“For Jesus knew from the beginning, who they were that did not believe, and who he was, that would betray him” (John 6:65
“When Jesus had said these things, he was troubled in spirit; and he testified, and said: Amen, amen I say to you, one of you shall betray me” (John 12:21
Men, brethren, the scripture must needs be fulfilled, which the Holy Ghost spoke before by the mouth of David concerning Judas, who was the leader of them that apprehended Jesus: who was numbered with us, and had obtained part of this ministry. And he indeed hath possessed a field of the reward of iniquity, and being hanged, burst asunder in the midst: and all his bowels gushed out. And it became known to all the inhabitants of Jerusalem: so that the same field was called in their tongue, Haceldama, that it to say, the field of blood. For it is written in the book of Psalms: Let their habitation become desolate, and let there be none to dwell therein. And his bishopric let another take. (Acts 1:16-20. Cf. Psalm 68:26; 108:8
