Deuteronomy 28:32, 68

Thy sons and thy daughters shall be given unto another people; and thine eyes shall look, and fail with longing for them all the day: and there shall be nought in the power of thy hand.

And Jehovah will bring thee into Egypt again with ships, by the way whereof I said unto thee, Thou shalt see it no more again: and there ye shall sell yourselves unto your enemies for bondmen and for bondwomen, and no man shall buy you.
