I'm looking for the tune to this ballad, which is labelled as being Child 23. The first verse is:

It was on a shere Thursday that our Lord aras Ful mild were the wordes he spak to Judas: "Judas, thou moste to Jerusalem, our mete for to bigge Thirtty platten of silver thou bere upon thy rigge."

Gotta love Middle English! *grin*
