John 6:70-71

6:70 Jesus replied, “Didn’t I choose you, the twelve, and yet one of you is the devil?” 6:71 (Now he said this about Judas son of Simon Iscariot, for Judas, one of the twelve, was going to betray him.)

John 12:4-6

12:4 But Judas Iscariot, one of his disciples (the one who was going to betray him) said, 12:5 “Why wasn’t this oil sold for three hundred silver coins and the money given to the poor?” 12:6 (Now Judas said this not because he was concerned about the poor, but because he was a thief. As keeper of the money box, he used to steal what was put into it.)
