When Jesus understood it
The indignation of his disciples at this action of the woman's; which he might know, as man, partly by their looks, and partly by their words; though without these, as God, he knew the secret indignation, and private resentment of their minds:
he said unto them, why trouble ye the woman?
by blaming her, and censuring the action she had done; as it must, no doubt, greatly trouble her to meet with such treatment from the disciples of Christ: had any of the Pharisees blamed her conduct, it would have given her no pain or uneasiness; but that Christ's own disciples should show indignation at an action done by her from a sincere love to Christ, and to do honour to him, must cut her to the heart: and so it is when either ministers of the Gospel, or private believers, are blamed for their honest zeal in the cause of Christ, by any that profess to love him; this grieves them more than all the enemies of religion say or do unto them:
for she hath wrought a good work upon me;
upon his body, by pouring the ointment on it: the Persic version reads it, "according to my mind": it was done, in the faith of him, as the Messiah; it sprung from real and sincere love to him, and was designed for his honour and glory; and so had the essentials of a good work in it. This is the first part of our Lord's defence of the woman: he goes on in the next verse.
