10But Jesus, knowing this, said to them, "Why do you trouble the woman? For she has done a good work for me. 11For you always have the poor with you; but you don`t always have me. 12For in that she poured this ointment on my body, she did it to prepare me for burial. 13Most assuredly I tell you, wherever this gospel will be preached in the whole world, what this woman has done will also be spoken of for a memorial of her."
