Are you sure a lot of the Old Testament isn't the insane ramblings of some psychotic warlord?

Lo, a day shall come for the Lord when the spoils shall be divided in your midst. And I will gather all the nations against Jerusalem for battle: the city shall be taken, houses plundered, women ravished; half of the city shall go into exile, but the rest of the people shall not be removed from the city. (Zechariah 14:1-2 NAB)
