1 Maccabees 8:26-32

26 And to those at war with her, the Jews shall not give or supply food, arms, money, or ships, as was agreed in Rome. The Jews must carry out their obligations without receiving anything in return.
27 "In the same way, if war is declared first against the Jewish nation, the Romans will come to their aid with hearty support, as the situation may require.
28 And to their enemies there shall not be given or supplied food, arms, money, or ships, as was agreed in Rome. The Romans must carry out their obligations without deception.
29 "These are the terms of the treaty that the Romans have made with the Jewish people.
30 But if, in the future, both parties shall agree to add or remove anything, they shall act on their decision, and whatever they add or remove shall be valid.
31 "Furthermore, concerning the wrongs which King Demetrius is doing against the Jews, we have written him as follows, "Why have you treated our friends and allies, the Jews, so harshly?
32 If they complain to us about you one more time, we will support their cause and go to war against you on land and sea.' "
