IV Maccabees 3:13

13 and unperceived by the guardians of the gate, they went throughout the whole camp of the enemy in quest.

IV Maccabees 3:13 In-Context

11 but a certain irrational longing for the water in the enemy's camp grew stronger and fiercer upon him, and consumed him with languish.
12 Wherefore his body-guards being troubled at this longing of the king, two valiant young soldiers, reverencing the desire of the king, put on their panoplies, and taking a pitcher, got over the ramparts of the enemies:
13 and unperceived by the guardians of the gate, they went throughout the whole camp of the enemy in quest.
14 And having boldly discovered the fountain, they filled out of it the draught for the king.
15 But he, though parched with thirst, reasoned that a draught reputed of equal value to blood, would be terribly dangerous to his soul.
