luke 22:3 Then entered Satan into Judas surnamed Iscariot, being of the number of the twelve. - Free Bible Online

      3. Then entered Satan, &c.--but not yet in the full sense. The awful stages of it were these: (1) Covetousness being his master--passion, the Lord let it reveal itself and gather strength by entrusting him with "the bag" (Joh 12:6), as treasurer to Himself and the Twelve. (2) In the discharge of that most sacred trust he became "a thief," appropriating its contents from time to time to his own use. Satan, seeing this door into his heart standing wide open, determines to enter by it, but cautiously (2Co 2:11); first merely "putting it into his heart to betray Him" (Joh 13:2), suggesting the thought to him that by this means he might enrich himself. (3) This thought was probably converted into a settled purpose by what took place in Simon's house at Bethany. (See Mt 26:6, and see on Joh 12:4-8.) (4) Starting back, perhaps, or mercifully held back, for some time, the determination to carry it into immediate effect was not consummated till, sitting at the paschal supper, "Satan entered into him" (see on Joh 13:27), and conscience, effectually stifled, only rose again to be his tormentor. What lessons in all this for every one (Eph 4:27; Jas 4:7; 1Pe 5:8, 9)!
