“They shall be a sign and a wonder against you and your offspring forever. 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. 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, a hard-faced nation who shall not respect the old or show mercy to the young.” Deuteronomy 28:46-50
