Deuteronomy 28:49-53

28:49 The Lord will raise up a distant nation against you, one from the other side of the earth as the eagle flies, a nation whose language you will not understand, 28:50 a nation of stern appearance that will have no regard for the elderly or pity for the young. 28:51 They will devour the offspring of your livestock and the produce of your soil until you are destroyed. They will not leave you with any grain, new wine, olive oil, calves of your herds, or lambs of your flocks until they have destroyed you. 28:52 They will besiege all of your villages until all of your high and fortified walls collapse – those in which you put your confidence throughout the land. They will besiege all your villages throughout the land the Lord your God has given you. 28:53 You will then eat your own offspring, the flesh of the sons and daughters the Lord your God has given you, because of the severity of the siege by which your enemies will constrict you.
