Which holy book calls for murder and enslavement?

"THE holy book is clear about what to do when you capture a city: “Put to the sword all the men in it”. As for the women and children, “You may take these as plunder for yourselves.” ...Besides, imagine if Christians and Jews still followed the letter of the Bible, which is, incidentally, the source of the passage at the top of this article. The verse (Deuteronomy 20:10-20) also prescribes that in case of capturing a city from the Hittites, Amorites, Canaanites, Perizzites, Hivites or Jebusites, the victors should “utterly destroy them” and “save alive nothing that breatheth”."
