Six days before Passover, Jesus entered Bethany where Lazarus, so recently raised from the dead, was living.
Lazarus and his sisters invited Jesus to dinner at their home. Martha served. Lazarus was one of those sitting at the table with them.
Mary came in with a jar of very expensive aromatic oils, anointed and massaged Jesus' feet, and then wiped them with her hair. The fragrance of the oils filled the house.
Judas Iscariot, one of his disciples, even then getting ready to betray him, said,
"Why wasn't this oil sold and the money given to the poor? It would have easily brought three hundred silver pieces."
He said this not because he cared two cents about the poor but because he was a thief. He was in charge of their common funds, but also embezzled them.
Jesus said, "Let her alone. She's anticipating and honoring the day of my burial.
You always have the poor with you. You don't always have me."
Word got out among the Jews that he was back in town. The people came to take a look, not only at Jesus but also at Lazarus, who had been raised from the dead.
