Origen, on Josh 8:22

“And they also that had taken and set the city on fire, issuing out of the city to meet their own men, began to cut off the enemies who were surrounded by them. So that the enemies being cut off on both sides, not one of so great a multitude was saved.”

“You will read in the Holy Scriptures about the battles of the just ones, about the slaughter and carnage of murderers, and that the saints spare none of their deeply rooted enemies. If they do spare them, they are even charged with sin, just as Saul was charged because he had preserved the life of Agag king of Amalek. You should understand the wars of the just by the method I set forth above, that these wars are waged by them against sin. But how will the just ones endure if they reserve even a little bit of sin? Therefore, this is said of them: "They did not leave behind even one who might be saved or might escape."Do you perhaps not believe me that the battle is joined against our sin? Then believe Paul as he says, "Not yet to the shedding of blood have you resisted against sin." Do you see that the fight proposed for you is against sin and that you must complete the battle even to the shedding of blood? Is it not evident that the divine Scripture indicates these things, even as it habitually says, "Sanctify war," and, "You will fight the battle of the Lord"?”
