"And it shall come to pass, if thou wilt not hearken unto the voice of the L-rd, thy G-d, to observe to do all His commandments and His statutes which I command thee this day, that all the curses shall come upon thee and overtake thee ... The stranger in thy midst shall mount up above thee higher and higher and thou shalt come down lower and lower ... he shall be the head and thou shalt be the tail"
(Deuteronomy 28)
