Jesus is believed to have been betrayed by a man who received some payment from jewish, who was his name?

His name was Judas Iscariot.

Explanation:

Judas Iscariot was the disciple who betrayed Jesus. He was chosen to be one of the 12 apostles but decided to deliver Jesus into the hands of those who wanted to take his life. Judas's greed gave way to the devil and he became known in the Bible as a traitor.

Judas sought out the Jewish religious leaders and offered to give them Jesus in exchange for 30 silver coins. The perfect occasion came during the Passover feast on the night of the Last Supper. Jesus would spend some time alone in a garden with the disciples after dinner. With few people around, this was the opportunity his enemies needed to catch him without too many supporters to fight on his side.

an informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
