John 12:31

Then Jesus six days before the passover came to Bethany, where Lazarus was, which had been dead, whom he raised from the dead.

There they made him a supper; and Martha served: but Lazarus was one of them that sat at the table with him.

Then took Mary a pound of ointment of spikenard, very costly, and anointed the feet of Jesus, and wiped his feet with her hair: and the house was filled with the odour of the ointment.

Then saith one of his disciples, Judas Iscariot, Simon’s son, which should betray him,

Why was not this ointment sold for three hundred pence, and given to the poor?
