And Judas Iscariot, one of the twelve
Apostles of Christ; who was the principal person that had indignation at the woman, and murmured against her, for the profusion of the ointment:
went unto the chief priests;
as soon as this affair was over, and Christ had defended the woman's conduct to his shame and silence: he immediately went out of the house, where they were, and set out from Bethany to Jerusalem; and understanding the chief priests were in consultation together at Caiaphas's house, how to apprehend Jesus, and put him to death, went directly to them, unsent for, and unthought of by them:
to betray him unto them;
which Satan had put into his heart, and what his avarice and revenge for the late action of the woman, and Christ's defence of it, prompted him to; (See Gill on Matthew 26:14).
