John 12: 1-3 (NRSVUE)
Six days before the Passover Jesus came to Bethany, the home of Lazarus, whom he had raised from the dead. 2 There they gave a dinner for him. Martha served, and Lazarus was one of those reclining with him. 3 Mary took a pound of costly perfume made of pure nard, anointed Jesus’s feet, and wiped them with her hair. The house was filled with the fragrance of the perfume.
