Bede : He ordered him to be taken into the camp. And in this place, and in this whole narration, wherever the name of the camp is positioned, it must be taught that it is placed in the singular in Greek: for this reason the Latin interpreter preferred to place it in the plural, lest, if he placed it in the singular, the sense of the reader would be carried far elsewhere, and instead of the assembly of the army and soldiers, a fortified place would be understood. So also in the Psalm where it is said: And they fell in the midst of their camps; in Greek παραβολὴ is written in the singular number. — Retractions on Acts
