3 That's when Satan entered Judas, the one called Iscariot. He was one of the Twelve. 4 Leaving the others, he conferred with the high priests and the Temple guards about how he might betray Jesus to them. 5 They couldn't believe their good luck and agreed to pay him well.
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.
