The Passion according to Mark begins like this (Chapter 14):
It was two days before the Passover and the festival of Unleavened Bread. The chief priests and the scribes were looking for a way to arrest Jesus by stealth and kill him; for they said, "Not during the festival, or there may be a riot among the people."This woman's name has been lost to history, but she has been vindicated nonetheless. She believed Jesus was who he said he was, and she covered him head to toe in a gesture of love and adoration, surely knowing that the people present would mock her for her foolishness. Jesus defended her, and every word he spoke was true. He died later that week, the poor are still with us, the story has been retold countless times, and billions and billions of people throughout history have heard what this woman did out of love for her king. She was no fool.
While he was at Bethany in the house of Simon the leper, as he sat at the table, a woman came with an alabaster jar of very costly ointment of nard, and she broke open the jar and poured the ointment on his head. But some were there who said to one another in anger, "Why was the ointment wasted in this way? For this ointment could have been sold for more than three hundred denarii, and the money given to the poor." And they scolded her. But Jesus said, "Let her alone; why do you trouble her? She has performed a good service for me. For you always have the poor with you, and you can show kindness to them whenever you wish; but you will not always have me. She has done what she could; she has anointed my body beforehand for its burial. Truly I tell you, wherever the good news is proclaimed in the whole world, what she has done will be told in remembrance of her."
