Deuteronomy 28:47-50

47Because you didn’t serve the Lord your God with joy and a cheerful heart, even though you had an abundance of everything,

48you will serve your enemies that the Lord will send against you, in famine, thirst, nakedness, and a lack of everything. He will place an iron yoke on your neck until he has destroyed you.

49The Lord will bring a nation from far away, from the ends of the earth, to swoop down on you like an eagle, a nation whose language you won’t understand,

50a ruthless nation, showing no respect for the old and not sparing the young.
