If a man be found who hath stolen one of his brethren of the children of Israel, and who hath treated him as a slave and sold him, that thief shall die; and thou shalt put evil away from thy midst.

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