3 Then Satan entered into Judas called Iscariot, who was one of the twelve; 4 he went away and conferred with the chief priests and officers of the temple police about how he might betray him to them. 5 They were greatly pleased and agreed to give him money.
Matthew Henry's Commentary on Luke 22:3-5
Commentary on Luke 22:1-6
(Read Luke 22:1-6)
Christ knew all men, and had wise and holy ends in taking Judas to be a disciple. How he who knew Christ so well, came to betray him, we are here told; Satan entered into Judas. It is hard to say whether more mischief is done to Christ's kingdom, by the power of its open enemies, or by the treachery of its pretended friends; but without the latter, its enemies could not do so much evil as they do.
