Verily I say unto you, Wheresoever this gospel shall be preached throughout the whole world, this also that she hath done shall be spoken of for a memorial of her.

And Judas Iscariot, one of the twelve, went unto the chief priests, to betray him unto them.

And when they heard it, they were glad, and promised to give him money. And he sought how he might conveniently betray him.
