John 6:68-71

⁶⁸Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life.

⁶⁹And we have believed and know that thou art the Holy One of God.

⁷⁰Jesus answered them, Did not I choose you the twelve, and one of you is a devil?

⁷¹Now he spake of Judas the son of Simon Iscariot, for he it was that should betray him, being one of the twelve.
