Library Eusebius of Caesarea Preparation for the Gospel
Book 12, Chapter 41
AGAIN when Moses says: 'But if the thief be found breaking in, and be smitten that he die, it is not murder,'[120] Plato agrees in this also, saying:
[PLATO] [121] 'If a man catch a thief coming into his house by night to steal his goods, and slay him, let him be guiltless: also if he kill a footpad in self-defence, let him be guiltless.'
