 Augustine insists, against the Manichees, that the God of the Old Testament is the same God as the God of the New Testament. One of the most striking differences between the two testaments was in relation to warfare. In the Old Testament God permits, in fact requires, the Israelites to engage in massacres. In the land God has given to the Israelites, the inhabitants of a city that surrenders will be enslaved, but if the city resists, “you shall not leave a single soul alive”  (Deuteronomy 20:11, 16).  “You must utterly destroy them; you shall make no covenant with them, and show no mercy to them”  (Deuteronomy 7:2).  If in some Israelite city some inhabitants practice idolatry, “you shall surely put the inhabitants of that city to the sword, destroying it utterly, all who are in it and its cattle”  (Deuteronomy 13:16).  Moses himself carried out a massacre of Israelites who had practiced idolatry  (Exodus 32:25–9).  Moses was angry when the Israelites spared women and children, and ordered them to kill all the prisoners except the virgins, whom they could keep for themselves  (Numbers 31:13–18).  Samuel was angry with Saul when the army let some animals live; for that sin, God deprived Saul of the kingdom  (1 Samuel 15).  Samuel himself hewed a prisoner to pieces  (1 Kings 15:32–3).  In the New Testament, in contrast, Christ says: “if one strike thee on thy right cheek, turn to him also the other”  (Matthew 5:39).  Can the New Testament be reconciled with the Old Testament? On Augustine’s view, the two Testaments must be reconcilable, since everything in the Bible is true.
