And Jesus said, Let her alone; why trouble ye her? she hath wrought a good work on me.
He begins by saying that the woman has done “a good work.” This is a technical term. It means almsgiving, putting up strangers, visiting the sick, burying the dead or the like.
According to Rabbi. Simlai, of the second half of the 3rd century A.D., the Torah opens with “a good work,” God clothing the naked, and concludes with one, God burying Moses.
