Deuteronomy 28:46-50 Amplified Bible (AMP)

46. They shall be upon you for a sign [of warning to other nations] and for a wonder, and upon your descendants forever.

47. Because you did not serve the Lord your God with joyfulness of [mind and] heart [in gratitude] for the abundance of all [with which He had blessed you],

48. Therefore you shall serve your enemies whom the Lord shall send against you, in hunger and thirst, in nakedness and in want of all things; and He will put a yoke of iron upon your neck until He has destroyed you.

49. The Lord will bring a nation against you from afar, from the end of the earth, as swift as the eagle flies, a nation whose language you shall not understand,

50. A nation of unyielding countenance who will not regard the person of the old or show favor to the young,
