Augustus Caesar was supportive of the continuation of the Jewish traditions of worship and lifestyle in recognition of their allegiance-or at least the lack of opposition-displayed during the reign of his father and other previous Roman rulers. In his Edict of Augustus on Jewish Rights, he established the principle that anyone caught stealing Jewish sacred books or funds from a synagogue or home would be punished by having his/her personal property seized and sent to the public treasury in Rome. See http://www.enotes.com/history/discuss/augustus-caesar-119147 for the text of the Edict.
Augustus was like Julius Caesar in his relatively friendly policies towards Jews. Julius Caesar had issued a variety of laws guaranteeing Jewish freedom to worship. Augustus renewed these laws. He even did things like exempting Jews from having to appear in court on the Sabbath. Here's a link that might be useful.
