1 Maccabees 12:1-7

1 When Jonathan saw that things were working out to his advantage, he chose ambassadors and sent them to Rome to confirm and renew friendship with the Romans.
2 He also sent letters with a similar message to Sparta and other places.
3 The ambassadors went to Rome, where they were admitted to the Senate chamber, and reported that the High Priest Jonathan and the Jewish nation had sent them to renew the earlier ties of friendship and alliance with Rome.
4 The Romans provided them with letters to the authorities in each country through which they would pass, guaranteeing them safe conduct in their return to the land of Judea.
5 Here is a copy of the letter Jonathan wrote to the Spartans:
6 "Jonathan the High Priest, the national council of leaders, the priests, and the rest of the people of Judea, to our brothers in Sparta, greetings.
7 At an earlier time, your King Arius sent a letter to our High Priest Onias, stating that our two nations are related, as the attached copy shows.
