II Maccabees 11:30

30 Wherefore they that will depart shall have safe conduct till the thirtieth day of Xanthicus with security.

II Maccabees 11:30 In-Context

28 If ye fare well, we have our desire; we are also in good health.
29 Menelaus declared unto us, that your desire was to return home, and to follow your own business:
30 Wherefore they that will depart shall have safe conduct till the thirtieth day of Xanthicus with security.
31 And the Jews shall use their own kind of meats and laws, as before; and none of them any manner of ways shall be molested for things ignorantly done.
32 I have sent also Menelaus, that he may comfort you.
