Mark 14:10
Then Judas Iscariot, one of the Twelve, went to the chief priests to betray Jesus to them — the juxtaposition is deliberate: the anointing woman follows immediately by Judas's betrayal. One gave everything; one sells the one who gave everything. One of the Twelve — the repeated identification of Judas as one of the Twelve marks the betrayal's depth. Judas is not an outsider or an enemy but one of the inner circle, one of the chosen twelve, one who was sent out with authority to heal and preach.
