Deuteronomy 28:47-50

47“1Because you did not serve the Lord your God with joy and a glad heart, for the abundance of all things; 48therefore you shall serve your enemies whom the Lord will send against you, 2in hunger, in thirst, in nakedness, and in the lack of all things; and He 3will put an iron yoke on your neck until He has destroyed you.

49“4The Lord will bring a nation against you from afar, from the end of the earth, 5as the eagle swoops down, a nation whose language you shall not understand, 50a nation of fierce countenance who will 6have no respect for the old, nor show favor to the young.
