Caesarius of Arles : Behold true and perfect charity: he ordered the death of a few people in order to save six hundred thousand, with the women and children excepted. If he had not been aroused with zeal for God to punish a few men, God's justice would have destroyed them all. — SERMON 40.1 Ephrem the Syrian : For the sons of Levi ran upon them, those who ran to [help] Moses and girded on their swords. For the sons of Levi did not know whom they should slay, because those that worshipped were mingled with those that worshipped not. But He, for Whom it was easy to distinguish, distinguished those who were defiled from those who were not defiled; so that the innocent might give thanks that their innocence had not passed [unseen by] the Just One; and the guilty might be convicted that their offence had not escaped [the eye of] the Judge. But the sons of Levi were the open avengers. Accordingly Moses set a mark upon the offenders, that it might be easy for the avengers to avenge. For the draught of the calf entered those in whom the love of the calf was dwelling, and displayed in them a manifest sign, that the drawn sword might rush upon them. — HOMILY ON OUR LORD 6 Gregory the Dialogist : Let them hear how Moses, when he saw that God was angry with His people, and commanded swords to be taken for executing vengeance, declared those to be on God's side who should smite the crimes of the offenders without delay, saying, If any man is the Lord's, let him join himself to me; put every man his sword upon his thigh; go in and out from gate to gate through the midst of the camp, and slay every man his brother and friend and neighbour. For to put sword upon thigh is to set earnestness in preaching before the pleasures of the flesh; so that, when any one is earnest to speak holy words, he must needs have a care to subdue illicit suggestions. But to go from gate to gate is to run to and fro with rebuke from vice to vice, even to every one by which death enters in unto the soul. And to pass through the midst of the camp is to live with such impartiality within the Church that one who reproves the sins of offenders turns aside to shew favour to none. Whence also it is rightly added, slay every man his brother and friend and neighbour. He in truth slays brother and friend and neighbour who, when he finds what is worthy of punishment, spares not even those whom he loves on the score of relationship from the sword of his rebuke. If, then, he is said to be God's who is stirred up by the zeal of divine love to smite vices, he surely denies himself to be God's who refuses to rebuke the life of the carnal to the utmost of his power. — The Book of Pastoral Rule, Part 3, Chapter 25
