Mark 14:6

‘But Jesus said, “Leave her alone. Why do you bother her? She has wrought a good work on me.” '

Jesus stepped in and intervened, telling them to stop upsetting the woman (so the muttering had become apparent to all). He pointed out that what she had done had uplifted Him and helped Him to face the future. She had ‘wrought a good work on Him'. He saw her ministration as from His Father.

‘A good work.' We might translate ‘a beautiful (kalon) work'. An act of tender generosity.
