John 12:1-7

Jesus therefore six days before the passover came to Bethany, where Lazarus was, whom Jesus raised from the dead. So they made him a supper there: and Martha served; but Lazarus was one of them that sat at meat with him. Mary therefore took a pound of ointment of pure nard, very precious, and anointed the feet of Jesus, and wiped his feet with her hair: and the house was filled with the odor of the ointment. But Judas Iscariot, one of his disciples, that should betray him, saith, Why was not this ointment sold for three hundred shillings, and given to the poor? Now this he said, not because he cared for the poor; but because he was a thief, and having the bag took away what was put therein. Jesus therefore said, Suffer her to keep it against the day of my burying.
