Judas stood outside the hall but was able to look around the corner and see what was happening. He heard Caiaphas, the chief priest condemn the man he had betrayed. As he observed Flavius lead a bound Jesus with orders to take him to Pontius Pilate, Judas realized the enormity of what he had done. He had betrayed an innocent man and now he had just been condemned by the Sanhedrin. As he held the sack containing the thirty pieces of silver, Judas knew what he had to do.
As Flavius led the bound Jesus out of the hall, Judas walked in and walked up to Caiaphas and some of the Elders. Judas said " I have sinned by betraying innocent blood".
" What is that to us" Caiaphas replied as he pointed a finger at Judas " you see to it".
A very frustrated Judas threw the sack containing the thirty pieces of silver at Caiaphas's feet and he stormed out of the hall. Flavius later heard that he had gone and hanged himself.
Caiaphas picked up the sack and said " It is not lawful to put this into the treasury because they are the price of blood". Caiaphas and the others discussed and decided to buy the potter's field to bury stranger's in.
