Deuteronomy 28:49-52

49The Lord will bring a nation against you from far away, from the end of the earth, swooping down like the eagle, a nation whose language you do not understand,

50a hard-faced nation who shall not respect the old or show mercy to the young.

51It shall eat the offspring of your cattle and the fruit of your ground, until you are destroyed; it also shall not leave you grain, wine, or oil, the increase of your herds or the young of your flock, until they have caused you to perish.

52"They shall besiege you in all your towns, until your high and fortified walls, in which you trusted, come down throughout all your land. And they shall besiege you in all your towns throughout all your land, which the Lord your God has given you.
