Flavius Josephus, The Wars of the Jews
William Whiston, A.M., Ed.

[340] AND now the Romans searched for Josephus, both out of the hatred they bore him, and because their general was very desirous to have him taken; for he reckoned that if he were once taken, the greatest part of the war would be over. They then searched among the dead, and looked into the most concealed recesses of the city; but as the city was first taken, he was assisted by a certain supernatural providence; for he withdrew himself from the enemy when he was in the midst of them, and leaped into a certain deep pit, whereto there adjoined a large den at one side of it, which den could not be seen by those that were above ground; and there he met with forty persons of eminency that had concealed themselves, and with provisions enough to satisfy them for not a few days. So in the day time he hid himself from the enemy, who had seized upon all places, and in the night time he got up out of the den and looked about for some way of escaping, and took exact notice of the watch; but as all places were guarded every where on his account, that there was no way of getting off unseen, he went down again into the den. Thus he concealed himself two days; but on the third day, when they had taken a woman who had been with them, he was discovered. Whereupon Vespasian sent immediately and zealously two tribunes, Paulinus and Gallicanus, and ordered them to give Josephus their right hands as a security for his life, and to exhort him to come up.
