ANNAS: Your help in this matter won’t go unrewarded.

CAIAPHAS: We’ll pay you in silver — cash on the nail.
We just need to know where the soldiers can find him.

ANNAS: With no crowd around him.

CAIAPHAS:Then we can’t fail.

JUDAS: I don’t need your blood money!

CAIAPHAS: Oh, that doesn’t matter, our expenses are good.

JUDAS: I don’t want your blood money!

ANNAS: But you might as well take it. We think that you should.

CAIAPHAS: Think of the things you could do with that money,
Choose any charity — give to the poor.
We’ve noted your motives — we’ve noted your feelings.
This isn’t blood money — it’s a fee, nothing —
Fee, nothing — fee, nothing more.

The movie version reverses the order of "need" and "want your blood money." It also turns the last lines into a brief interchange between Caiaphas and Annas:

CAIAPHAS: This isn't isn't blood money -- it's ...
ANNAS: A fee.
CAIAPHAS: A fee, nothing more.
