When the people heard how Rome and Sparta had praised Simon, they wanted to thank him, too. An official public decree was issued outlining his achievements--risking his life, contributing great sums of his own money, serving as leader and high priest, maintaining justice and loyalty. King Demetrius made him one of his Friends.
The Jews gave him authority over the sanctuary and the appointment of all officials. Read verses 44-49 again. No one is allowed to reverse any of his decisions. Anyone that doesn't go along with what he has decided shall be liable to punishment. And he is also the high priest.
