2 Maccabees 15:17

Thus being well comforted by the words of Judas, which were very good, and able to stir them up to valour, and to encourage the hearts of the young men, they determined not to pitch camp, but courageously to set upon them, and manfully to try the matter by conflict, because the city and the sanctuary and the temple were in danger.
