Holy war

Extracted from the Wikipedia article Religious war.
Judaism
"Holy war" is a Western concept referring to war that is fought for religion, against adherents of other religions, often in order to promote religion through conversion, and with no specific geographic limitation. This concept does not occur in the Hebrew Bible, whose wars are not fought for religion or in order to promote it but, rather, in order to preserve religion and a religiously unique people in relation to a specific and limited geography.
