{Satan entered into Judas} (eis(886c)then eis Ioudan).
Ingressive aorist active indicative. Satan was now renewing his
attack on Jesus suspended temporarily ( Lu 4:13 ) "until a good
chance." He had come back by the use of Simon Peter ( Mr 8:33  Mt
16:23 ). The conflict went on and Jesus won ultimate victory ( Lu
10:18 ). Now Satan uses Judas and has success with him for Judas
allowed him to come again and again ( Joh 13:27 ). Judas
evidently opened the door to his heart and let Satan in. Then
Satan took charge and he became a devil as Jesus said ( Joh
6:70 ). This surrender to Satan in no way relieves Judas of his
moral responsibility.
