Deuteronomy 28:48-50, NLT

48you will serve your enemies whom the Lord will send against you. You will be left hungry, thirsty, naked, and lacking in everything. The Lord will put an iron yoke on your neck, oppressing you harshly until he has destroyed you.

49“The Lord will bring a distant nation against you from the end of the earth, and it will swoop down on you like a vulture. It is a nation whose language you do not understand, 50a fierce and heartless nation that shows no respect for the old and no pity for the young.
