I Maccabees 8:19-29

19 They went therefore to Rome, which was a very great journey, and came into the senate, where they spake and said.
20 Judas Maccabeus with his brethren, and the people of the Jews, have sent us unto you, to make a confederacy and peace with you, and that we might be registered your confederates and friends.
21 So that matter pleased the Romans well.
22 And this is the copy of the epistle which the senate wrote back again in tables of brass, and sent to Jerusalem, that there they might have by them a memorial of peace and confederacy:
23 Good success be to the Romans, and to the people of the Jews, by sea and by land for ever: the sword also and enemy be far from them,
24 If there come first any war upon the Romans or any of their confederates throughout all their dominion,
25 The people of the Jews shall help them, as the time shall be appointed, with all their heart:
26 Neither shall they give any thing unto them that make war upon them, or aid them with victuals, weapons, money, or ships, as it hath seemed good unto the Romans; but they shall keep their covenants without taking any thing therefore.
27 In the same manner also, if war come first upon the nation of the Jews, the Romans shall help them with all their heart, according as the time shall be appointed them:
28 Neither shall victuals be given to them that take part against them, or weapons, or money, or ships, as it hath seemed good to the Romans; but they shall keep their covenants, and that without deceit.
29 According to these articles did the Romans make a covenant with the people of the Jews.
