Deuteronomy 28 (ESV)
47 Because you did not serve the Lord your God with joyfulness and gladness of heart, because of the abundance of all things, 48 therefore you shall serve your enemies whom the Lord will send against you, in hunger and thirst, in nakedness, and lacking everything. And he will put a yoke of iron on your neck until he has destroyed you. 49 The 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, 50 a hard-faced nation who shall not respect the old or show mercy to the young. 51 It 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.
