Most Christians today totally reject the idea of Holy War, but in the Old Testament, there are numerous accounts of battles in which the ancient Israelites clearly believed that God was on their side. When the Israelites reached the Promised Land, God commanded them to make war on the people who lived there: “In the cities of the nations the Lord your God is giving you as an inheritance, do not leave alive anything that breathes. Completely destroy them.” (Deuteronomy)
