In those days Peter stood up among the believers (a group numbering about 120) and said, 'Brothers, the Scripture had to be fulfilled which the Holy Spirit spoke long ago through the mouth of David concerning Judas, who served as guide for those who arrested Jesus - he was one of our number and shared in this ministry.
(With the reward he got for his wickedness, Judas bought a field; there he fell headlong, his body burst open and all his intestines spilled out. Everyone in Jerusalem heard about this, so they called the field, 'Field of Blood')
Peter said, 'For it is written in the book of Psalms, 'May his place be deserted; let there be no one to dwell in it.'"
It is amazing that David prophesied about Judas long before it happened. The Holy Spirit revealed to him that one who walked with the apostles would lead to the arrest of Jesus. Even Jesus predicted the actions of Judas, but none the less it was Judas' choice. Even at the end of his life, there is no record of Judas asking for forgiveness for his sinful actions. (Peter did say, 'the Scripture HAD to be fulfilled.')
