Deuteronomy 28:51-52

51They will devour the young of your livestock and the crops of your land until you are destroyed. They will leave you no grain, new wine or olive oil, nor any calves of your herds or lambs of your flocks until you are ruined. 52They will lay siege to all the cities throughout your land until the high fortified walls in which you trust fall down. They will besiege all the cities throughout the land the Lord your God is giving you.
