Clement of Alexandria : At any rate [Scripture] says openly, "You shall not loathe Egyptians, since you lived as strangers in Egypt." By Egyptian it means "Gentile," in fact anyone from anywhere in the world. It is further forbidden to think of enemies as enemies, even if they are presently besieging your walls in the effort to capture your city, until you have sent them an envoy to invite them to peace. — The Stromata Book 2
